Each polynomial should be expanded from factored form, simplified and written in descending order of exponents on the variable.

For example: (x+5)(x-2) should be given as the answer x^2 + 3x - 10

degree 4; zeros -3, 1, 3, 5

please help!

X=1, X-1 = 0.

X=3, X-3 = 0.

X=5, X-5 = 0.

(X+3)(X-1)(X-3)(X-5)= 0,

(X^2+2X-3)(X^2-8X+15) = 0,

X^4-8X^3+15X^2+2X^3-16X^2+30X-3X^2+24X-45,

Combine like-terms and get:

X^4-6X^3-4X^2+54X-45 = 0.
