Check my answers please? 1. Write the equation of a polynomial that has zeros at –3 and 2. Equation: f(x) = (x+3)(x-2) --------------------------------------- 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 trinomial---Correct 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 trinomial-----Correct 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 (x-4)(2x²+5x+2) The first prob can also be done with synthetic division. P(-3): just substitute x=-3: -2(-3)^4-3(-3)^3-(-3)+4=... (I'm going to sleep now - it's 11:35 pm in Holland - got to work early tomorrow)
