The given trinomial can be factored using factorization as
x²-x-12
=x²-4x+3x-12
=x(x-4)+3(x-4)
=(x-4)(x+3)
Thus x-4 and x+3 are the factors of the given trinomial. From these we can see x+3 is listed in option A
So the answer to this question is Option A
C is false. 9 multiplied by 7 equals 63.
I would say go with with B
We want to find the product:
.
By the
, we distribute
over each of the three terms inside the parenthesis:
.
Multiplying the coefficients, and adding the exponents we get:
.
Answer:
.
