I'll be sure to vote the best answer.
26.) Simplify:
(x3 + 4x2 - 2x + 5) - (3x3 - 3x2 + x - 2) =
Ax3 + 3x2 + 3x + 1
Bx3 + 3x2 + 3x + 1
C-2x3 + 7x2 - 3x + 7
D2x3 - 8x2 - 8x + 11

27.) Solve for x:
2x2 + 3x - 1 = 0
A(-5 ± ?13) / 2
B(-7 ± ?13) / 4
C(-3 ± ?17) / 2
D(-3 ± ?17) / 4

28.) What's missing in this factorization?
x2 + 7x + 10

(x + 2)(____)
Ax + 5
B5x + 6
Cx + 1
D2x - 5

29.) Solve for y.
3(y - 4) = 4y + 2 - y
A 0
B1
