Question

Could some one help me work out these problems

Answer 1

x=-2,0,1
x=0,4,-1/2
Write the polynomial given the zeros for each problem

Answer 2

I already know the answers
1.(x(x+2(x-1)
2.x(x-4)92x+1)
but I need to show my work, the reason I know my answers is because are teacher gave us the answer key because it's just a study guide. But I need to know how to get them.

Answer 3

HI!!

Answer 4

you can multiply out if you like

Answer 5

the reasoning is this: if \(r\) is a zero of \(p(x)\) then \(x-r\) is a factor of \(p(x)\)

Answer 6

that is why if \(-2,0,2\) are zeros it factors as
\[(x-(-2))(x-0)(x-2)\] or just \[(x+2)x(x-2)\]

Answer 7

Oh okay, thank you.
