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


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

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

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

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

Combine like terms: -1x + 6x = 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
