Question

How do you find a polynomial function with zeroes 5,-3?

Answer 1

The requested polynomial is `x^2-2x-15`

Explanation:

If it is a polynomial like this

`(x-5)(x-(-3))=(x-5)*(x+3)=x^2+3x-5x-15=x^2-2x-15`

Generally if you have roots `r_1,r_2` the polynomial is given by

`(x-r_1)*(x-r_2)`
