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
