The video tutorial explains how to solve a quadratic equation by finding two numbers that multiply to -48 and add to -2. The teacher attempts various factor pairs before identifying 6 and -8 as the correct pair. The equation is then rewritten as (x + 6)(x - 8) = 0, and each factor is set to zero to solve for x, resulting in solutions x = -6 and x = 8.

What is the product of the two numbers we are trying to find?

• -48

• -2

• 48

• 2

Which pair of numbers correctly factors -48 and adds up to -2?

• 8 and -6

• 6 and -8

• 4 and -12

• 2 and -24

What is the rewritten form of the quadratic expression using the factors found?

• (x + 6)(x + 8)

• (x - 6)(x + 8)

• (x + 6)(x - 8)

• (x - 6)(x - 8)
