Answer this question…A. x4 + 2x3 + 9x2 + 4 B. x4 + 4x3 + 9x2 + 4 C. x4 + 2x3 + 9x2 + 4x + 4 D. x4 + 2x3 + 9x2 - 4x + 4

9x2+9x-12 All I can do is simplify this. I can't solve it unless turn this expression into an equation.

It is 4x^2 + 10x - 1

6x - 12 + 4x + 5 = 06x + 4x = 12 - 510x = 7x = 7/10

4x + 8 + 7x + 12 = 11x + 20

It is 4x^2 + 10x - 1

3x3 + 192 = 3*(x3 + 64) = 3*(x + 4)*(x2 - 4x + 16)

-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.

6x - 12 + 4x + 5 = 06x + 4x = 12 - 510x = 7x = 7/10

4x + 8 + 7x + 12 = 11x + 20

8x + 15

It is: y = -4x+12

If: 4x+(-12) = 8 then 4x = 20 and x = 5

4[x+3]=4x+12 4x+12=4x+12 it's open.

2x + 6x + 4x = 12x
