Solution for 1500=x(x+10)(30-2x) equation:


Simplifying
1500 = x(x + 10)(30 + -2x)

Reorder the terms:
1500 = x(10 + x)(30 + -2x)

Multiply (10 + x) * (30 + -2x)
1500 = x(10(30 + -2x) + x(30 + -2x))
1500 = x((30 * 10 + -2x * 10) + x(30 + -2x))
1500 = x((300 + -20x) + x(30 + -2x))
1500 = x(300 + -20x + (30 * x + -2x * x))
1500 = x(300 + -20x + (30x + -2x2))

Combine like terms: -20x + 30x = 10x
1500 = x(300 + 10x + -2x2)
1500 = (300 * x + 10x * x + -2x2 * x)
1500 = (300x + 10x2 + -2x3)

Solving
1500 = 300x + 10x2 + -2x3

Solving for variable 'x'.

Reorder the terms:
1500 + -300x + -10x2 + 2x3 = 300x + -300x + 10x2 + -10x2 + -2x3 + 2x3

Combine like terms: 300x + -300x = 0
1500 + -300x + -10x2 + 2x3 = 0 + 10x2 + -10x2 + -2x3 + 2x3
1500 + -300x + -10x2 + 2x3 = 10x2 + -10x2 + -2x3 + 2x3

Combine like terms: 10x2 + -10x2 = 0
1500 + -300x + -10x2 + 2x3 = 0 + -2x3 + 2x3
1500 + -300x + -10x2 + 2x3 = -2x3 + 2x3

Combine like terms: -2x3 + 2x3 = 0
1500 + -300x + -10x2 + 2x3 = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(750 + -150x + -5x2 + x3) = 0

Ignore the factor 2.
