Araceli Robbins · Answer 2

Factor and use the zero product property. To factor, find two numbers that multiply to + 12 and add to - 7. These two numbers are - 4 and - 3

So,

x^2 - 7x + 12 = 0

(x-4) (x-3) = 0

x-4 = 0 or x-3 = 0

x = 4 or x = 3

Answer is choice B

Solve x2 - 7x + 12 = 0.a. x = - 3, x = - 4b. x = 3, x = 4c. x = 2, x = 6d. x = - 2, x = - 6

Solve x2 - 7x + 12 = 0.

a. x = - 3, x = - 4

b. x = 3, x = 4

c. x = 2, x = 6

d. x = - 2, x = - 6
