Simplifying (3x + 1)(x + -1) = 0 Reorder the terms: (1 + 3x)(x + -1) = 0 Reorder the terms: (1 + 3x)(-1 + x) = 0 Multiply (1 + 3x) * (-1 + x) (1(-1 + x) + 3x * (-1 + x)) = 0 ((-1 * 1 + x * 1) + 3x * (-1 + x)) = 0 ((-1 + 1x) + 3x * (-1 + x)) = 0 (-1 + 1x + (-1 * 3x + x * 3x)) = 0 (-1 + 1x + (-3x + 3x2)) = 0 Combine like terms: 1x + -3x = -2x (-1 + -2x + 3x2) = 0 Solving -1 + -2x + 3x2 = 0 Solving for variable 'x'. Factor a trinomial. (-1 + -3x)(1 + -1x) = 0Subproblem 1
Set the factor '(-1 + -3x)' equal to zero and attempt to solve: Simplifying -1 + -3x = 0 Solving -1 + -3x = 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 + -3x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -3x = 0 + 1 -3x = 0 + 1 Combine like terms: 0 + 1 = 1 -3x = 1 Divide each side by '-3'. x = -0.3333333333 Simplifying x = -0.3333333333Subproblem 2
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 = 1Solution
x = {-0.3333333333, 1}
