Question

Select the correct answer.
What is the factored form of this expression?
x2 - 7x + 12

Answer 1

(x-4)(x-3)

Explanation:

x²- 7x+12

=x²-4x-3x+12 applying midterm break

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

=(x-4)(x-3)

Answer 2

x = 3, x= 4 are the factors of the equation.

Explanation:

x² - 7 x + 12 = 0

x² -4 x - 3 x + 12 = 0

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

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

x = 3, x = 4

Hence x = 3, x= 4 are the factors of the equation.
