Solution for =(x-2)(3x+1) equation: 


Simplifying
0 = (x + -2)(3x + 1)

Reorder the terms:
0 = (-2 + x)(3x + 1)

Reorder the terms:
0 = (-2 + x)(1 + 3x)

Multiply (-2 + x) * (1 + 3x)
0 = (-2(1 + 3x) + x(1 + 3x))
0 = ((1 * -2 + 3x * -2) + x(1 + 3x))
0 = ((-2 + -6x) + x(1 + 3x))
0 = (-2 + -6x + (1 * x + 3x * x))
0 = (-2 + -6x + (1x + 3x2))

Combine like terms: -6x + 1x = -5x
0 = (-2 + -5x + 3x2)

Solving
0 = -2 + -5x + 3x2

Solving for variable 'x'.

Combine like terms: 0 + 2 = 2
2 + 5x + -3x2 = -2 + -5x + 3x2 + 2 + 5x + -3x2

Reorder the terms:
2 + 5x + -3x2 = -2 + 2 + -5x + 5x + 3x2 + -3x2

Combine like terms: -2 + 2 = 0
2 + 5x + -3x2 = 0 + -5x + 5x + 3x2 + -3x2
2 + 5x + -3x2 = -5x + 5x + 3x2 + -3x2

Combine like terms: -5x + 5x = 0
2 + 5x + -3x2 = 0 + 3x2 + -3x2
2 + 5x + -3x2 = 3x2 + -3x2

Combine like terms: 3x2 + -3x2 = 0
2 + 5x + -3x2 = 0
