Find the equation of the quadratic function with zeros at -1 and 1 and a vertex at (0,-6)

A polynomial with zeroes at -1 and 1 is a multiple of

So, your polynomial is something like

We can determine the value of a by imposing the passage through (0,-6):

So, the function is

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
