A1 Final Review: Chapters 8-12

True or false:  $-x^3=\left(-x\right)^3$  

Classify the expression as a monomial, binomial, trinomial, other polynomial, or not a polynomial. Then state the degree of the polynomial.
 $-3x^3y+9x^2y+6y$  

• trinomial

• not a polynomial

• degree 4

• degree 3

• degree 8

Simplify, leaving each answer in positive exponential form.
 $\frac{24x^2y^{-3}}{\left(2x^{-1}y^2\right)^3}$  

Write a function rule (equation) for the graph of  $y=x^3$ that  is  translated down 4 units and right 5 units.

How much money is in an account that earns 6% COMPOUNDED quarterly if $10,000 deposited and there are no withdrawals or additional deposits for 10 years? Round to the nearest dollar.

Find the difference. 
(3- 2x + 2x²) - (4x -5 +3x²)

• x_² + 6x + 8
• 2x² + 5x - 7
• -x² -6x + 8
• -2x² + 11x - 4

Simplify.
 $\left(x+8\right)^2$  

Multiply
(x²-2x+1)(x+1)

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