Learn how to use a rectangle to factor and solve a quadratic equation

The video tutorial explains how to solve a quadratic equation using the box and diamond methods. It begins by setting the equation to zero and then demonstrates the box method to organize terms. The diamond method is used to find factors that multiply to a*c and add to b. The middle term is split accordingly, and the equation is factored completely. Finally, the zero product property is applied to find the roots of the equation.

What is the first step in solving the equation 2X^2 + 7X = -3?

• Multiply both sides by 2

• Add 3 to both sides

• Subtract 3 from both sides

• Divide both sides by 7

In the box method, where is the first term placed?

• Upper right corner

• Lower left corner

• Upper left corner

• Bottom right corner

What is the purpose of the diamond method in factoring?

• To simplify the equation by removing terms

• To find two numbers that multiply to a*c and add to b

• To find the sum of a and c

• To divide the equation by a constant

Which two numbers multiply to give 6 and add to give 7 in the diamond method?

• 6 and 1

• 5 and 2

• 2 and 3

• 3 and 4

What are the factors of the quadratic equation 2X^2 + 7X + 3 = 0?

• (X + 2)(2X + 1)

• (2X + 3)(X + 1)

• (X + 3)(2X + 1)

• (X + 1)(2X + 3)

What is the solution for X when using the zero product property on (X + 3)(2X + 1) = 0?

• X = -3 and X = -1/2

• X = -3 and X = 1/2

• X = 3 and X = 1/2

• X = 3 and X = -1/2

Why is it important to rewrite the quadratic equation as a product equal to zero?

• To simplify the equation

• To apply the zero product property

• To find the sum of the roots

• To eliminate fractions
