Solution for x^2=(x+4)(x-3) equation:


Simplifying
x2 = (x + 4)(x + -3)

Reorder the terms:
x2 = (4 + x)(x + -3)

Reorder the terms:
x2 = (4 + x)(-3 + x)

Multiply (4 + x) * (-3 + x)
x2 = (4(-3 + x) + x(-3 + x))
x2 = ((-3 * 4 + x * 4) + x(-3 + x))
x2 = ((-12 + 4x) + x(-3 + x))
x2 = (-12 + 4x + (-3 * x + x * x))
x2 = (-12 + 4x + (-3x + x2))

Combine like terms: 4x + -3x = 1x
x2 = (-12 + 1x + x2)

Add '-1x2' to each side of the equation.
x2 + -1x2 = -12 + 1x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
0 = -12 + 1x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
0 = -12 + 1x + 0
0 = -12 + 1x

Solving
0 = -12 + 1x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1x' to each side of the equation.
0 + -1x = -12 + 1x + -1x
Remove the zero:
-1x = -12 + 1x + -1x

Combine like terms: 1x + -1x = 0
-1x = -12 + 0
-1x = -12

Divide each side by '-1'.
x = 12

Simplifying
x = 12
