Question

5) The roots of y = (x + 2)(x – 3) are -2 and 3. Write an equation in trinomial form for the quadratic function whose roots are -4 and 6.

Answer 1

Answer: x^2 - 2x - 24

Explanation:

So you can put it back into factored form the easiest by switching the signs.

(x + 4)(x - 6) = y

Then you can use the foil method to put it back into trinomial form.

x^2 - 2x - 24
