Question

How do you find a polynomial function that has zeros x=-2 and degree n=2?

Answer 1

`x^2 +4x +4`

Explanation:

Zero is x=-2, means that x+2 would be a factor of the polynomial. Since it is of degree2, there would be two repeated zeros . Hence the polynomial would be `(x+2)^2` , or `x^2 +4x+4`
