Answer:
(x + 9)² = 36
Step-by-step explanation:
Given
x² + 18x + 57 = 12 ( subtract 57 from both sides )
x² + 18x = - 45
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(9)x + 81 = - 45 + 81
(x + 9)² = 36

Solve for m:
8 = m/4
8 = m/4 is equivalent to m/4 = 8:
m/4 = 8
Multiply both sides of m/4 = 8 by 4:
(4 m)/4 = 4×8
(4 m)/4 = 4/4×m = m:
m = 4×8
4×8 = 32:
Answer: m = 32 thus m - 12 = 32 -12 = 20
