Answer:
(x + 8)2 • (3x - 1)
Step-by-step explanation:
The first term is, 3x2 its coefficient is 3 .
The middle term is, +23x its coefficient is 23 .
The last term, "the constant", is -8
Step-1 : Multiply the coefficient of the first term by the constant 3 • -8 = -24
Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is 23 .
-24 + 1 = -23
-12 + 2 = -10
-8 + 3 = -5
-6 + 4 = -2
-4 + 6 = 2
-3 + 8 = 5
-2 + 12 = 10
-1 + 24 = 23 That's it
