Simplifying
x2 + -4ax = 4a(a + -1x)
Reorder the terms:
-4ax + x2 = 4a(a + -1x)
-4ax + x2 = (a * 4a + -1x * 4a)
Reorder the terms:
-4ax + x2 = (-4ax + 4a2)
-4ax + x2 = (-4ax + 4a2)
Add '4ax' to each side of the equation.
-4ax + 4ax + x2 = -4ax + 4ax + 4a2
Combine like terms: -4ax + 4ax = 0
0 + x2 = -4ax + 4ax + 4a2
x2 = -4ax + 4ax + 4a2
Combine like terms: -4ax + 4ax = 0
x2 = 0 + 4a2
x2 = 4a2
Solving
x2 = 4a2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Simplifying
x2 = 4a2
Take the square root of each side:
