Question

Select the two binomials that are factors of this trinomial below .

Answer 1

Answer:

C. x – 4

D. x + 3

Step-by-step explanation:

Given trinomial,

$x^2-x-12$

By middle term spitting,

$x^2-(4-3)x-12$

$x^2-4x+3x-12$

$x(x-4)+3(x-4)$

$(x+3)(x-4)$

⇒ Only binomials x + 3 and x - 4 are the factors of the given trinomial.

Options 'C' and 'D' are correct.

Answer 2

x^2-x-12

factor

what 2 numbers multiply to get -12 and add to get -1?

-4 and 3

(x-4)(x+3)

answer is C and D
