Question

1. SIMPLIFY EACH EXPRESSION:

8x2 - 7x + 4x3 - 2-3x2 + 9x - 4
5(7 + 3x) - 12
2[z + 3) + 3(5 – 3z)

Answer 1

1. 8x2 - 7x + 4x3 - 2-3x2 + 9x - 4 = 16+2x

Explanation:

1. Multiply all the multiplication problems (should look like this --> 16-7x+12-2-6+9x-4)

2. Calculate the sum or difference (should end up looking like this --> 16-7x+9x) and then into this (16 +2x)

Bringing us to the answer → 16 + 2x!
