Unit 5 Test Review

Classifying, Adding, Subtracting and Multiplying Polynomials

Use this review to update your notecard as needed

Classifying Polynomials

Degree - this is the highest exponent
Terms - how many terms (different variables or a constant) are there?
Will be on test - table may be helpful on notecard

Multiple Choice

9x⁴

Quadratic polynomial

Quartic monomial

Quadratic monomial

Cubic monomial

Multiple Choice

v²- 3v + 4

Quadratic, trinomial

Quadratic, binomial

Quartic, polynomial

Quartic, trinomial

Adding/Subtracting Polynomials

Distribute subtraction sign, if needed
Combine like terms - same variable and same exponent
Put into standard form

Subtract

Distribute subtraction sign
7p²+ 3p - 5p²- 4
Combine Like Terms and put into Standard Form
2p² + 3p - 4

Multiple Choice

Find the sum.

(2x² + 5x - 7) + ( 3 - 4x² + 6x)

2x²+ 3x +1

-2x²- 11x -4

2x²+ 5x -7

-2x² + 11x -4

Monomial Times Polynomial

Distribute monomial to ALL terms.
When multiplying with exponents - multiply coefficients, add exponents
Combine Like Terms and put into Standard Form

Simplify

Distribute z to the binomial
5z² -3z
Bring down remaining term
5z²- 3z - 2z
Combine like terms and put into standard form
5z² -z

Multiple Choice

Simplify the expression

-6x - 5(10x + 3)

-56x - 15

-56x+15

44x+15

-44x-15

Multiplying Polynomials

Expand if needed - (x-4)² is (x-4)(x-4)
If 2 binomials - FOIL
First, Inner, Outer, Last
If binomial and trinomial - distribute 1st term to all terms and then 2nd term to all terms
Combine like terms and put into standard form

Simplify

Distribute 1st term of binomial to all terms in trinomial
4x³ -28x² + 4x
Distribute 2nd term of binomial to all terms in trinomial
-x² + 7x +1
Combine like terms and put into standard form
4x³ - 29x² + 11x + 1

Multiple Choice

Multiply
(x+5)²

x²+25

x²-25

x²+10x+25

x²-10x+25

Multiple Choice

(5x+2)(x²-3x+6)

5x³- 17x²+24x +12

5x³+ 17x² - 24x +12

5x³ - 13x² + 24x +12

5x³ +13x² - 24x - 12
