Question

1. what is the polynomial function in standard form with zeroes 1,2,-2, and -3
A x^2+2x^3+7x^2-8x+12
B. X^4+2x^3-7x^2-8x+12
C. X^4+2x^3-7x^2+8x+12
D. x^4+2x^3+7x^2+8x+12
2. what are the zeroes of the function? what are their multiplicities?
f(x)=5x^3-5x^2-30x
A. the number 3,-2,and 0 are zeros of multiplicity 1
B. The numbers 3,-2, and 0 are zeros of multiplicity 2
C. the numbers -3 , 2, and 0 are zeroes of multiplicity 1
D. the numbers -3,2, and 0 are zeros of multiplicity 2

Answer 1

if 1, 2, -2 and -3 are all the zeroes the your polynomial is
\[ f(x)=(x-1)(x-2)(x+2)(x+3) \]
just multiply

Answer 2

do you just do the foil method ?
