Simplifying 3x2 + -6 = 3x2 + -12 Reorder the terms: -6 + 3x2 = 3x2 + -12 Reorder the terms: -6 + 3x2 = -12 + 3x2 Add '-3x2' to each side of the equation. -6 + 3x2 + -3x2 = -12 + 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 -6 + 0 = -12 + 3x2 + -3x2 -6 = -12 + 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 -6 = -12 + 0 -6 = -12 Solving -6 = -12 Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
