Question

find a degree 3 polynomial with zeros -2, 1, 5 and go through point (0, -3)

Answer 1

Did u tried that?

Answer 2

yeah help

Answer 3

x^3-4x^2-7x+10

Answer 4

how did you figure that out

Answer 5

Well, since -2,1,5 are zeros. Then they must be...
x+2=0
x-1=0
x-5=0
Since all those would equal to 0.
Then you just multiply the three. (x+2)(x-1)(x-5). And you get the answer.
