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


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

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

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

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

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

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

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

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

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

Solving
3x + 2x2 = 0
