Alg 1: Unit 1 Retest

Add the following polynomials:
(x³-2x²+3)+(2x³+3x²-1)

• 3x³-2x²+3x+2
• 3x³+x²+2
• 3x³-5x²-2
• 3x³-x²+1

Solve for x:

• x = yb - v
• x = by - v
• x = by + v

What is the first step in solving this equation?

• subtract 3 to both sides

• subtract the 6 - 2

• distribute 2

• distribute -2

Simplify the expression:
6 + 2(7x - 3) 

• 12 + 7x
• 14x
• 14x + 3
• 9 + 7x

Simplify the Expression. 
9z  - 21 - 3z + 10

• Simplified
• 9z - 21 - 7
• 9z - 11 -3z
• 6z - 11
