Solution for L(x)=(0.2x^3+5x^2+25x)-(0.2x^3-4x^2+48x+100) equation: 


Simplifying
L(x) = (0.2x3 + 5x2 + 25x) + -1(0.2x3 + -4x2 + 48x + 100)

Multiply L * x
xL = (0.2x3 + 5x2 + 25x) + -1(0.2x3 + -4x2 + 48x + 100)

Reorder the terms:
xL = (25x + 5x2 + 0.2x3) + -1(0.2x3 + -4x2 + 48x + 100)

Remove parenthesis around (25x + 5x2 + 0.2x3)
xL = 25x + 5x2 + 0.2x3 + -1(0.2x3 + -4x2 + 48x + 100)

Reorder the terms:
xL = 25x + 5x2 + 0.2x3 + -1(100 + 48x + -4x2 + 0.2x3)
xL = 25x + 5x2 + 0.2x3 + (100 * -1 + 48x * -1 + -4x2 * -1 + 0.2x3 * -1)
xL = 25x + 5x2 + 0.2x3 + (-100 + -48x + 4x2 + -0.2x3)

Reorder the terms:
xL = -100 + 25x + -48x + 5x2 + 4x2 + 0.2x3 + -0.2x3

Combine like terms: 25x + -48x = -23x
xL = -100 + -23x + 5x2 + 4x2 + 0.2x3 + -0.2x3

Combine like terms: 5x2 + 4x2 = 9x2
xL = -100 + -23x + 9x2 + 0.2x3 + -0.2x3

Combine like terms: 0.2x3 + -0.2x3 = 0.0
xL = -100 + -23x + 9x2 + 0.0
xL = -100 + -23x + 9x2

Solving
xL = -100 + -23x + 9x2

Solving for variable 'x'.

Reorder the terms:
100 + 23x + xL + -9x2 = -100 + -23x + 9x2 + 100 + 23x + -9x2

Reorder the terms:
100 + 23x + xL + -9x2 = -100 + 100 + -23x + 23x + 9x2 + -9x2

Combine like terms: -100 + 100 = 0
100 + 23x + xL + -9x2 = 0 + -23x + 23x + 9x2 + -9x2
100 + 23x + xL + -9x2 = -23x + 23x + 9x2 + -9x2

Combine like terms: -23x + 23x = 0
100 + 23x + xL + -9x2 = 0 + 9x2 + -9x2
100 + 23x + xL + -9x2 = 9x2 + -9x2

Combine like terms: 9x2 + -9x2 = 0
100 + 23x + xL + -9x2 = 0
