Simplifying 3(1 + -1x) + 4(x2 + -1) = -3x + -1 + 2(1 + 2x2) (1 * 3 + -1x * 3) + 4(x2 + -1) = -3x + -1 + 2(1 + 2x2) (3 + -3x) + 4(x2 + -1) = -3x + -1 + 2(1 + 2x2) Reorder the terms: 3 + -3x + 4(-1 + x2) = -3x + -1 + 2(1 + 2x2) 3 + -3x + (-1 * 4 + x2 * 4) = -3x + -1 + 2(1 + 2x2) 3 + -3x + (-4 + 4x2) = -3x + -1 + 2(1 + 2x2) Reorder the terms: 3 + -4 + -3x + 4x2 = -3x + -1 + 2(1 + 2x2) Combine like terms: 3 + -4 = -1 -1 + -3x + 4x2 = -3x + -1 + 2(1 + 2x2) -1 + -3x + 4x2 = -3x + -1 + (1 * 2 + 2x2 * 2) -1 + -3x + 4x2 = -3x + -1 + (2 + 4x2) Reorder the terms: -1 + -3x + 4x2 = -1 + 2 + -3x + 4x2 Combine like terms: -1 + 2 = 1 -1 + -3x + 4x2 = 1 + -3x + 4x2 Add '3x' to each side of the equation. -1 + -3x + 3x + 4x2 = 1 + -3x + 3x + 4x2 Combine like terms: -3x + 3x = 0 -1 + 0 + 4x2 = 1 + -3x + 3x + 4x2 -1 + 4x2 = 1 + -3x + 3x + 4x2 Combine like terms: -3x + 3x = 0 -1 + 4x2 = 1 + 0 + 4x2 -1 + 4x2 = 1 + 4x2 Add '-4x2' to each side of the equation. -1 + 4x2 + -4x2 = 1 + 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 -1 + 0 = 1 + 4x2 + -4x2 -1 = 1 + 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 -1 = 1 + 0 -1 = 1 Solving -1 = 1 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.
