Hi there! :)
[tex]\large\boxed{f(x) = (x + 2)^{2} - 64}[/tex]
f(x) = x² + 4x - 60
Rewrite:
0 = x² + 4x - 60
Complete the square by creating a perfect square trinomial. Make sure to add the third term to both sides:
0 + 4 = (x² + 4x + 4) - 60
Rewrite the trinomial as a square binomial:
4 = (x + 2)² - 60
Subtract 4 from both sides:
0 = (x +2)² - 64
Rewrite:
f(x) = (x + 2)² - 64
