How to factor a trinomial when a is one

The video tutorial explains the process of factoring trinomials by reversing the multiplication of binomials. It introduces the concept of using area to find side lengths of a rectangle, representing trinomials with boxes. The instructor guides students through identifying factors of a quadratic equation, emphasizing the importance of understanding the relationship between terms and their factors. The tutorial concludes with a detailed explanation of the box method for factoring, encouraging students to practice this technique.

What is the main goal when given the area of a rectangle in the context of factoring?

• To find the perimeter of the rectangle

• To determine the two side lengths

• To calculate the volume of the rectangle

• To identify the color of the rectangle

In the box method, how many boxes are used to represent a trinomial with three terms?

• Five boxes

• Four boxes

• Three boxes

• Two boxes

When splitting the middle term of a trinomial, what should the two new terms do?

• Multiply to give the constant term

• Add to give the middle term

• Divide to give the constant term

• Subtract to give the middle term

What is the first step recommended when finding factors of a number?

• Start with the smallest factors

• Guess the factors

• Use a calculator

• Start with the largest factors

Why must both factors be negative if they multiply to a positive number but add to a negative number?

• Because positive times positive is negative

• Because negative times negative is positive

• Because positive plus positive is negative

• Because negative plus negative is positive
