5) (7 + 8x – 2x4) – (x4 + 3x2 – 1)
9-6
Simplify. Show one work step. For 6-10, leave in order given. For 11-12 write in D.O.
6) 3x(x2 + 6x + 10)
7) 5x2y3(3x3 + 2x5 - 8y)
8) ½x5(12x13 + 8x4y3 – 2x2y)
9) z4(wx + x2y – 3xz + z4)
10) -7y(2xy + 9x2 – 6y2)
11) 4x(3x2 + 6) – x2(5 – 4x)
12) 3xy(2x + 7) + 8x(6 – 7y)
Solve and check.
13) (2x + 3) – (5x – 7) = 1
14) (2x2 – x + 6) – 2(x2 – 3x + 5) = 11
15) ⅘(25x – 15) = 18x – 22
16) 8x +11 = 4 + 5(2x – 1)
17) 4(3 + 2x) – 6(4x + 3) = 3(x + 3) + 4
