Solution for (x+1)(x-1)=x(4x-3)-1 equation:


Simplifying
(x + 1)(x + -1) = x(4x + -3) + -1

Reorder the terms:
(1 + x)(x + -1) = x(4x + -3) + -1

Reorder the terms:
(1 + x)(-1 + x) = x(4x + -3) + -1

Multiply (1 + x) * (-1 + x)
(1(-1 + x) + x(-1 + x)) = x(4x + -3) + -1
((-1 * 1 + x * 1) + x(-1 + x)) = x(4x + -3) + -1
((-1 + 1x) + x(-1 + x)) = x(4x + -3) + -1
(-1 + 1x + (-1 * x + x * x)) = x(4x + -3) + -1
(-1 + 1x + (-1x + x2)) = x(4x + -3) + -1

Combine like terms: 1x + -1x = 0
(-1 + 0 + x2) = x(4x + -3) + -1
(-1 + x2) = x(4x + -3) + -1

Reorder the terms:
-1 + x2 = x(-3 + 4x) + -1
-1 + x2 = (-3 * x + 4x * x) + -1
-1 + x2 = (-3x + 4x2) + -1

Reorder the terms:
-1 + x2 = -1 + -3x + 4x2

Add '1' to each side of the equation.
-1 + 1 + x2 = -1 + -3x + 1 + 4x2

Combine like terms: -1 + 1 = 0
0 + x2 = -1 + -3x + 1 + 4x2
x2 = -1 + -3x + 1 + 4x2

Reorder the terms:
x2 = -1 + 1 + -3x + 4x2

Combine like terms: -1 + 1 = 0
x2 = 0 + -3x + 4x2
x2 = -3x + 4x2

Solving
x2 = -3x + 4x2

Solving for variable 'x'.

Reorder the terms:
3x + x2 + -4x2 = -3x + 4x2 + 3x + -4x2

Combine like terms: x2 + -4x2 = -3x2
3x + -3x2 = -3x + 4x2 + 3x + -4x2

Reorder the terms:
3x + -3x2 = -3x + 3x + 4x2 + -4x2

Combine like terms: -3x + 3x = 0
3x + -3x2 = 0 + 4x2 + -4x2
3x + -3x2 = 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
3x + -3x2 = 0

Factor out the Greatest Common Factor (GCF), '3x'.
3x(1 + -1x) = 0

Ignore the factor 3.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(1 + -1x)' equal to zero and attempt to solve: Simplifying 1 + -1x = 0 Solving 1 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1x = 0 + -1 -1x = 0 + -1 Combine like terms: 0 + -1 = -1 -1x = -1 Divide each side by '-1'. x = 1 Simplifying x = 1

Solution

x = {0, 1}
