With factoring, completing the square, quadratic formula, and the square root method, it can be difficult to decide which method is most efficient in solving quadratic equations.

Do you remember the night before your child started high school? Entering the biggest world they’ve seen? Lying in bed, thoughts of peer pressure and difficult classes were swirling through your head, keeping you awake. Tossing and turning, you worried about the choices they’d make and the importance of their grades on their future college acceptance.

Fast forward to December of that year. They’ve completed their first semester of high school with good grades. You’re thrilled! But part of you remains hesitant of more challenging concepts and courses that lie ahead.

Recall in my last post, I introduced a girl who was deciding whether a private math tutor or a tutoring center would be a better fit for her to learn Algebra I. This is the math course most freshmen take in high school.

At our first session, Emily amazed me with how quickly she learned new problem-solving methods. She had never seen a system of equations but she devised a way to solve it! Her mathematical intuition left me wide-eyed, stumbling over my words. I could barely contain my excitement (never underestimate what someone can do!).

I tutored two other Algebra I students that year. They had Algebra class five days a week along with tutoring with me once or twice a week. Emily was in Pre-Algebra in school, so she only learned Algebra one hour a week with me.

After one month of tutoring, Emily was ahead of the other Algebra students. With only tutoring once a week. The personalization of private tutoring, focusing only on topics she needed to further develop, allowed for us to cover a full week’s worth of content in one session.

Not only was the pace quick, but her test scores proved she mastered the content. I gave her the same tests I gave my former Algebra I classes. On each test she earned an A.

By December, we slowed down the pace, but we were still halfway through the curriculum. We were able to keep up the pace of a normal Algebra class meeting only one hour a week.

We finished the Algebra curriculum in April and began to review for her Algebra placement exam.

### Even Advanced Students Encounter Challenges

My stomach dropped as I read an email from Emily’s mom:

“Emily was pretty upset about the review when she came home today. She felt like she forgot everything…Do you think she understands most of the concepts in Algebra 1? I don't want to push her ahead if she really isn't ready.”

If Emily wasn’t prepared for the placement exam, I blamed myself. I should have reviewed concepts more consistently throughout the year. Did her mom just waste money on 8 months of tutoring?

During that previous review session, I could see Emily’s discouragement as she aggressively erased wrong answers. Her shoulders slouched more with every question she couldn’t correctly solve.

Math came naturally to her and she was used to excelling in it. She had high expectations of her math abilities and she was frustrated. It was the first time in her life that she encountered math topics she didn’t fully understand.

During that review session, I suppressed my fear that she hadn’t retained anything I taught her. As soon as I gave her a clue word or the first step, she had an "Oh yeah!" response. The information was all there, she needed to review to remind herself.

Between sessions, I encouraged her to review on her own. To look back through one chapter of session notes each week.

I gave her mini quizzes at the next tutoring session. She didn’t need as much guidance solving problems on the quiz. With each correct answer, I regained hope.

### How to Solve Quadratic Equations

After 5 more tutoring sessions, I gave her a post-assessment. The results were greatly improved in most topics, but she still hadn’t mastered quadratics. I provided Emily with videos and practice problems to study for her placement exam. I also created the diagram below to help her connect solving quadratic equations using different ways.

There are more analytical methods for solving quadratic equations other than factoring. Which method is most efficient?

1. Factoring—quickest method, but not always possible

2. Quadratic Formula—always works!

3. Completing the Square—if "b" is even

4. Square Root method—if no "b" term

To dive deeper into those methods, watch a video explaining more methods for solving quadratic equations. In the video, I provided example problems demonstrating how to use each method.

### Struggling as a Growth Opportunity

A month later I heard back from Emily’s mom. She placed out of Algebra I, performing “better than most current Algebra 2 students” would on the test.

Entering high school can be a scary time for both parents and students. Some students will easily ace every test. Others, even advanced students, will encounter a topic or subject that is difficult for them to grasp. Whether the struggle is in solving quadratic equations or not until differential equations in Calculus, they don’t have to go through the frustration of not understanding alone.

At Meryl’s Magic Math, we pride ourselves in explaining concepts as simply as possible and in multiple ways to ensure understanding. In tailoring the lesson to the student’s specific needs, we are able to work together to cover a full week’s worth of class content (and sometimes more!) in one hour.
