Solution for 0=(5x+3)(x-6) equation:


Simplifying
0 = (5x + 3)(x + -6)

Reorder the terms:
0 = (3 + 5x)(x + -6)

Reorder the terms:
0 = (3 + 5x)(-6 + x)

Multiply (3 + 5x) * (-6 + x)
0 = (3(-6 + x) + 5x * (-6 + x))
0 = ((-6 * 3 + x * 3) + 5x * (-6 + x))
0 = ((-18 + 3x) + 5x * (-6 + x))
0 = (-18 + 3x + (-6 * 5x + x * 5x))
0 = (-18 + 3x + (-30x + 5x2))

Combine like terms: 3x + -30x = -27x
0 = (-18 + -27x + 5x2)

Solving
0 = -18 + -27x + 5x2

Solving for variable 'x'.

Combine like terms: 0 + 18 = 18
18 + 27x + -5x2 = -18 + -27x + 5x2 + 18 + 27x + -5x2

Reorder the terms:
18 + 27x + -5x2 = -18 + 18 + -27x + 27x + 5x2 + -5x2

Combine like terms: -18 + 18 = 0
18 + 27x + -5x2 = 0 + -27x + 27x + 5x2 + -5x2
18 + 27x + -5x2 = -27x + 27x + 5x2 + -5x2

Combine like terms: -27x + 27x = 0
18 + 27x + -5x2 = 0 + 5x2 + -5x2
18 + 27x + -5x2 = 5x2 + -5x2

Combine like terms: 5x2 + -5x2 = 0
18 + 27x + -5x2 = 0
