Write a quadratic function with zeros 7 and –2.

Question

Write your answer using the variable x and in standard form with a leading coefficient of 1

Answer 1

Since the zeros are at x = 7 and x = -2, the quadratic function can be written as:

f(x) = (x - 7)(x + 2)
f(x) = x^2 - 5x - 14

So, the quadratic function in standard form with a leading coefficient of 1 is:
f(x) = x^2 - 5x - 14
