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

Step-by-step explanation:
Answer:
(- 2, 9 )
Step-by-step explanation:
Given a parabola in standard form, y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
y = - x² - 4x + 5 ← is in standard form
with a = - 1 and b = - 4, thus
= - = - 2
Substitute x = - 2 into equation for corresponding y- coordinate
y = - (- 2)² - 4(- 2) + 5 = - 4 + 8 + 5 = 9
vertex = (- 2, 9 )
