can someone help me with these probs. ?

2) Find the zeros for each equation. State the multiplicity of any zeros.
a. y = x4 + 2x3 + x2
b. y = x3 – 2x2 + x
c. y = (x2 – 3)(x2 + 3x – 4)
d. y = (x – 4)2(x + 3)3

3)Solve by graphing. Round to the nearest hundredth if needed.
a. 0 = x4 + 3x3 – 1
b. 0 = x3 – 3x2 + 2

4)Write a polynomial function with rational coefficients in standard form with zeros at 4, -5 and 8.

5)Divide using long division.
a. (2x3 – 3x2 – 18x – 8) / (x + 4)
b. (9x2 – 21x – 20) / (x – 1)
