Solution for P(x)-U(x)=(4x^2-1)-(x^2+2) equation: 


Simplifying
P(x) + -1U(x) = (4x2 + -1) + -1(x2 + 2)

Multiply P * x
xP + -1U(x) = (4x2 + -1) + -1(x2 + 2)

Multiply U * x
xP + -1xU = (4x2 + -1) + -1(x2 + 2)

Reorder the terms:
xP + -1xU = (-1 + 4x2) + -1(x2 + 2)

Remove parenthesis around (-1 + 4x2)
xP + -1xU = -1 + 4x2 + -1(x2 + 2)

Reorder the terms:
xP + -1xU = -1 + 4x2 + -1(2 + x2)
xP + -1xU = -1 + 4x2 + (2 * -1 + x2 * -1)
xP + -1xU = -1 + 4x2 + (-2 + -1x2)

Reorder the terms:
xP + -1xU = -1 + -2 + 4x2 + -1x2

Combine like terms: -1 + -2 = -3
xP + -1xU = -3 + 4x2 + -1x2

Combine like terms: 4x2 + -1x2 = 3x2
xP + -1xU = -3 + 3x2

Solving
xP + -1xU = -3 + 3x2

Solving for variable 'x'.

Reorder the terms:
3 + xP + -1xU + -3x2 = -3 + 3x2 + 3 + -3x2

Reorder the terms:
3 + xP + -1xU + -3x2 = -3 + 3 + 3x2 + -3x2

Combine like terms: -3 + 3 = 0
3 + xP + -1xU + -3x2 = 0 + 3x2 + -3x2
3 + xP + -1xU + -3x2 = 3x2 + -3x2

Combine like terms: 3x2 + -3x2 = 0
3 + xP + -1xU + -3x2 = 0

The solution to this equation could not be determined.
