Simplifying z(4z + 9) = 4z2 + 9z + -6 Reorder the terms: z(9 + 4z) = 4z2 + 9z + -6 (9 * z + 4z * z) = 4z2 + 9z + -6 (9z + 4z2) = 4z2 + 9z + -6 Reorder the terms: 9z + 4z2 = -6 + 9z + 4z2 Add '-9z' to each side of the equation. 9z + -9z + 4z2 = -6 + 9z + -9z + 4z2 Combine like terms: 9z + -9z = 0 0 + 4z2 = -6 + 9z + -9z + 4z2 4z2 = -6 + 9z + -9z + 4z2 Combine like terms: 9z + -9z = 0 4z2 = -6 + 0 + 4z2 4z2 = -6 + 4z2 Add '-4z2' to each side of the equation. 4z2 + -4z2 = -6 + 4z2 + -4z2 Combine like terms: 4z2 + -4z2 = 0 0 = -6 + 4z2 + -4z2 Combine like terms: 4z2 + -4z2 = 0 0 = -6 + 0 0 = -6 Solving 0 = -6 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.
