(2n2 + 4n + 4)(4n – 5)
= 8n^3 + 16n^2 +16n -10n^2 - 20n - 20
= 8n^3 +6n^2 -4n - 20
answer is d.
8n3 + 6n2 – 4n – 20
You put the x=6
6³-4(6)²-12(6)+15=15
9.2x10^-8
Move the decimal to the right 8 times. Since it is moved to the right, the exponent is negative.
I think the answer is D. But I am not sure if that's the right answer.
8c + 6-3c -2
8c -3c + 6-2 = 5c + 4
