Answer:
(x + -6)(x + -6) = -36
Step-by-step explanation:
Simplifying
x2 + -12x + 72 = 0
Reorder the terms:
72 + -12x + x2 = 0
Solving
72 + -12x + x2 = 0
Solving for variable 'x'.
Begin completing the square.
Move the constant term to the right:
Add '-72' to each side of the equation.
72 + -12x + -72 + x2 = 0 + -72
Reorder the terms:
72 + -72 + -12x + x2 = 0 + -72
Combine like terms: 72 + -72 = 0
0 + -12x + x2 = 0 + -72
-12x + x2 = 0 + -72
Combine like terms: 0 + -72 = -72
-12x + x2 = -72
The x term is -12x. Take half its coefficient (-6).
Square it (36) and add it to both sides.
Add '36' to each side of the equation.
-12x + 36 + x2 = -72 + 36
Reorder the terms:
36 + -12x + x2 = -72 + 36
Combine like terms: -72 + 36 = -36
36 + -12x + x2 = -36
Factor a perfect square on the left side:
(x + -6)(x + -6) = -36
Can't calculate square root of the right side.
The solution to this equation could not be determined.
