Answer:
(x + 7)² = 0
Step-by-step explanation:
Given
x² + 14x + 49 = 0 ( subtract 49 from both sides )
x² + 14x = - 49
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(7)x + 49 = - 49 + 49
(x + 7)² = 0
F(x)/g(x) is undefined where g(x) = 0. That occurs where x=2.
