Rewrite the function by completing the square f(x) =4x2+12x+9

Answer:
see explanation
Step-by-step explanation:
Given
f(x) = 4x² + 12x + 9
The coefficient of the x² term must be 1 so factor out 4 from the first 2 terms
f(x) = 4(x² + 3x) + 9
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² + 3x
f(x) = 4(x² + 2( )x + - ) + 9
= 4(x + )² - 9 + 9
= 4(x + )²
Thus
f(x) = 4x² + 12x + 9 = 4(x + )²
