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


Simplifying
2 = x(x + 1)

Reorder the terms:
2 = x(1 + x)
2 = (1 * x + x * x)
2 = (1x + x2)

Solving
2 = 1x + x2

Solving for variable 'x'.

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

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

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

Factor a trinomial.
(1 + -1x)(2 + x) = 0

Subproblem 1

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

Subproblem 2

Set the factor '(2 + x)' equal to zero and attempt to solve: Simplifying 2 + x = 0 Solving 2 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + x = 0 + -2 x = 0 + -2 Combine like terms: 0 + -2 = -2 x = -2 Simplifying x = -2

Solution

x = {1, -2}
