1. Write the equation of a polynomial that has zeros at –3 and 2.
Equation: f(x) = (x+3)(x2)

Write each polynomial function in standard form. Then classify it by degree and by the number of terms.
2. n = 4m2 – m + 7m4
n = 4m3 + 4m – 2; cubic trinomial
n = 7m4 + 4m2 – m; quartic trinomialCorrect
n = 4m4 + 8m2 – m ; quartic trinomial
n = 3m3 + 2m – 5; cubic trinomial

3. f(t) = 4t + 3t3 + 2t – 7
f(t) = 3t3 + 6t – 7; cubic trinomialCorrect
f(t) = 2t3 + 4t –

In the attachment, I would do a synthetic division: 4  2 3 18 8 8 20 8 ________________ + 2 5 2 0 SO it would be (x4)(2x²+5x+2) The first prob can also be done with synthetic division. P(3): just substitute x=3: 2(3)^43(3)^3(3)+4=... (I'm going to sleep now  it's 11:35 pm in Holland  got to work early tomorrow)
