Simplifying
(2x + -1) = 2x + -3x2
Reorder the terms:
(-1 + 2x) = 2x + -3x2
Remove parenthesis around (-1 + 2x)
-1 + 2x = 2x + -3x2
Add '-2x' to each side of the equation.
-1 + 2x + -2x = 2x + -2x + -3x2
Combine like terms: 2x + -2x = 0
-1 + 0 = 2x + -2x + -3x2
-1 = 2x + -2x + -3x2
Combine like terms: 2x + -2x = 0
-1 = 0 + -3x2
-1 = -3x2
Solving
-1 = -3x2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x2' to each side of the equation.
-1 + 3x2 = -3x2 + 3x2
Combine like terms: -3x2 + 3x2 = 0
-1 + 3x2 = 0
Add '1' to each side of the equation.
-1 + 1 + 3x2 = 0 + 1
Combine like terms: -1 + 1 = 0
0 + 3x2 = 0 + 1
3x2 = 0 + 1
Combine like terms: 0 + 1 = 1
3x2 = 1
Divide each side by '3'.
x2 = 0.3333333333
Simplifying
x2 = 0.3333333333
Take the square root of each side:
x = {-0.577350269, 0.577350269}
