Simplifying
(2x + 1)(2x + -1) = 99
Reorder the terms:
(1 + 2x)(2x + -1) = 99
Reorder the terms:
(1 + 2x)(-1 + 2x) = 99
Multiply (1 + 2x) * (-1 + 2x)
(1(-1 + 2x) + 2x * (-1 + 2x)) = 99
((-1 * 1 + 2x * 1) + 2x * (-1 + 2x)) = 99
((-1 + 2x) + 2x * (-1 + 2x)) = 99
(-1 + 2x + (-1 * 2x + 2x * 2x)) = 99
(-1 + 2x + (-2x + 4x2)) = 99
Combine like terms: 2x + -2x = 0
(-1 + 0 + 4x2) = 99
(-1 + 4x2) = 99
Solving
-1 + 4x2 = 99
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1' to each side of the equation.
-1 + 1 + 4x2 = 99 + 1
Combine like terms: -1 + 1 = 0
0 + 4x2 = 99 + 1
4x2 = 99 + 1
Combine like terms: 99 + 1 = 100
4x2 = 100
Divide each side by '4'.
x2 = 25
Simplifying
x2 = 25
Take the square root of each side:
x = {-5, 5}
