Simplifying
(x + 1)(x + 1) = 24

Reorder the terms:
(1 + x)(x + 1) = 24

Reorder the terms:
(1 + x)(1 + x) = 24

Multiply (1 + x) * (1 + x)
(1(1 + x) + x(1 + x)) = 24
((1 * 1 + x * 1) + x(1 + x)) = 24
((1 + 1x) + x(1 + x)) = 24
(1 + 1x + (1 * x + x * x)) = 24
(1 + 1x + (1x + x2)) = 24

Combine like terms: 1x + 1x = 2x
(1 + 2x + x2) = 24

Solving
1 + 2x + x2 = 24

Solving for variable 'x'.
