Answer:
D) x + 8
Step-by-step explanation:
factor. Find factors of x² & -48, in that, when combined, it will give 2x.
x² + 2x - 48
x -6
x 8
(x - 6)(x + 8)
Check. Follow FOIL method. Combine the first, outside, Inside, & Last terms:
(x * x) = x²
(x * 8) = 8x
(x * -6) = -6x
(-6 * 8) = -48
x² + 8x - 6x - 48
x² + 2x - 48 (√)
Your answer choices:
(x - 6) & (x + 8)
x + 8 shows up as a choice, so D) x + 8 is your answer.
~
(x + 8)(x - 6)
to factorise consider the factors of - 48 which sum to + 2
These are + 8 and - 6 thus
x² + 2x - 48 = (x + 8)(x - 6)
