Question

How can polynomial functions be written when given the zeros?

Answer 1

2x^2 + 2x - 0

Answer 2

I think.

Answer 3

well it can be written as the product of linear factors

if you know a polynomial has 2 unequal zeros at x = a and x = -b

then

x = a means x -a = 0 and (x - a) is a factor

x = -b means x + b = 0 and (x + b) is a factor

so

f(x) = (x -a)(x + b)
