2x^2 + 2x - 24
= 2x^2 + 8x - 6x -24
= 2x(x + 4) -6(x + 4)
= (x+4)(2x-6)
Answer:
.
Step-by-step explanation:
The trick here is to notice that all 3 terms can be div. by 2:
2(x^2 + x - 12)
Note that -12 factors into -3 * 4 or -4 * 3. Thus,
x^2 + x - 12 = (x-4)(x+3), and so 2x2 + 2x − 24 = 2(x-4)(x+3).
