(-6x2)(5x)
-30x3
What can you catch but not throw?
Cold
Classify the polynomial by the number of terms (provide the name): x3 + 2
Binomial
What does zero's of a function mean?
Zero's mean that the x-values make the expression =0
Sketch a graph of a polynomial that has two zeros.
a parabola whose vertex is below the x axis
What is the fundamental theorem of algebra? Give an example and explain. Write it down
The degree of a polynomial determine the number of solutions
A word I know, Six letters it contains. Subtract just one, and twelve is what remains.
Dozens
Classify the polynomial by degree (provide the name): 5x3 - 3x + 12

Candle
Write in standard form, then classify the polynomial by degree and number of terms (provide the names): 3x3 + 8 - x3 - 7x2
2x3 - 7x2 + 8; cubic trinomial
Write a polynomial function in standard form with the given zeros: 1, -1, -2
x3 + 2x2 - x - 2
Explain why finding a zero is the same as finding an x-intercept
Because the x-intercept is the value of x that makes the expression = 0
