Question

Write a polynomial if x-intercepts at x=2, and -3

Answer 1

y = x^2 +x -6

Explanation:

The two x intercepts would be represented in a polynomial with the expressions (x-2) and (x+3). [we know that each is equal to 0, the y-intercept].

Thus, we can build a polynomial by using both expressions, such as:

(x-2)*(x+3)

= x^2 +x -6
