Solution for (x+1)*(2x+3)=(2x+1)*(x-1) equation:


Simplifying
(x + 1)(2x + 3) = (2x + 1)(x + -1)

Reorder the terms:
(1 + x)(2x + 3) = (2x + 1)(x + -1)

Reorder the terms:
(1 + x)(3 + 2x) = (2x + 1)(x + -1)

Multiply (1 + x) * (3 + 2x)
(1(3 + 2x) + x(3 + 2x)) = (2x + 1)(x + -1)
((3 * 1 + 2x * 1) + x(3 + 2x)) = (2x + 1)(x + -1)
((3 + 2x) + x(3 + 2x)) = (2x + 1)(x + -1)
(3 + 2x + (3 * x + 2x * x)) = (2x + 1)(x + -1)
(3 + 2x + (3x + 2x2)) = (2x + 1)(x + -1)

Combine like terms: 2x + 3x = 5x
(3 + 5x + 2x2) = (2x + 1)(x + -1)

Reorder the terms:
3 + 5x + 2x2 = (1 + 2x)(x + -1)

Reorder the terms:
3 + 5x + 2x2 = (1 + 2x)(-1 + x)

Multiply (1 + 2x) * (-1 + x)
3 + 5x + 2x2 = (1(-1 + x) + 2x * (-1 + x))
3 + 5x + 2x2 = ((-1 * 1 + x * 1) + 2x * (-1 + x))
3 + 5x + 2x2 = ((-1 + 1x) + 2x * (-1 + x))
3 + 5x + 2x2 = (-1 + 1x + (-1 * 2x + x * 2x))
3 + 5x + 2x2 = (-1 + 1x + (-2x + 2x2))

Combine like terms: 1x + -2x = -1x
3 + 5x + 2x2 = (-1 + -1x + 2x2)

Add '-2x2' to each side of the equation.
3 + 5x + 2x2 + -2x2 = -1 + -1x + 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
3 + 5x + 0 = -1 + -1x + 2x2 + -2x2
3 + 5x = -1 + -1x + 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
3 + 5x = -1 + -1x + 0
3 + 5x = -1 + -1x

Solving
3 + 5x = -1 + -1x

Solving for variable 'x'.
