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


Simplifying
f(x) = (x + 1)(2x + -1)

Multiply f * x
fx = (x + 1)(2x + -1)

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

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

Multiply (1 + x) * (-1 + 2x)
fx = (1(-1 + 2x) + x(-1 + 2x))
fx = ((-1 * 1 + 2x * 1) + x(-1 + 2x))
fx = ((-1 + 2x) + x(-1 + 2x))
fx = (-1 + 2x + (-1 * x + 2x * x))
fx = (-1 + 2x + (-1x + 2x2))

Combine like terms: 2x + -1x = 1x
fx = (-1 + 1x + 2x2)

Solving
fx = -1 + 1x + 2x2

Solving for variable 'f'.
