Simplifying 3(2x2 + -1) = 7x Reorder the terms: 3(-1 + 2x2) = 7x (-1 * 3 + 2x2 * 3) = 7x (-3 + 6x2) = 7x Solving -3 + 6x2 = 7x Solving for variable 'x'. Reorder the terms: -3 + -7x + 6x2 = 7x + -7x Combine like terms: 7x + -7x = 0 -3 + -7x + 6x2 = 0 Factor a trinomial. (-1 + -3x)(3 + -2x) = 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 '(3 + -2x)' equal to zero and attempt to solve: Simplifying 3 + -2x = 0 Solving 3 + -2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -2x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -2x = 0 + -3 -2x = 0 + -3 Combine like terms: 0 + -3 = -3 -2x = -3 Divide each side by '-2'. x = 1.5 Simplifying x = 1.5Solution
x = {-0.3333333333, 1.5}
