Answer:
Answer choice b) 2x^4+11x^3+12x^2−10x−8
Step-by-step explanation:
(x^2+4x+2)(2x^2+3x+−4)
=(x^2)(2x^2)+(x^2)(3x)+(x^2)(−4)+(4x)(2x^2)+(4x)(3x)+(4x)(−4)+(2)(2x^2)+(2)(3x)+(2)(−4)
=2x^4+3x^3−4x^2+8x^3+12x^2−16x+4x^2+6x−8
2x^4+11x^3+12x^2−10x−8
Witch leave us with the answer choice B) 2x^4+11x^3+12x^2−10x−8
Its D. 3(-1+4)-(4÷-1)+3. This simplifies to 3(3)-(-4)+3, or 9+4+3
Hi ;-)
7/9 + 6/8 + 6/3 = 7/8 + 3/4 + 2 =
= 28/32 + 24/32 + 2 = 52/32 + 2 =
= 1 20/32 + 2 = 3 20/32 = 3 5/8
The answer i got was
n=-3/4,n=-1
