Simplifying 2z(4z + 11) = 8z2 + 22z + -9 Reorder the terms: 2z(11 + 4z) = 8z2 + 22z + -9 (11 * 2z + 4z * 2z) = 8z2 + 22z + -9 (22z + 8z2) = 8z2 + 22z + -9 Reorder the terms: 22z + 8z2 = -9 + 22z + 8z2 Add '-22z' to each side of the equation. 22z + -22z + 8z2 = -9 + 22z + -22z + 8z2 Combine like terms: 22z + -22z = 0 0 + 8z2 = -9 + 22z + -22z + 8z2 8z2 = -9 + 22z + -22z + 8z2 Combine like terms: 22z + -22z = 0 8z2 = -9 + 0 + 8z2 8z2 = -9 + 8z2 Add '-8z2' to each side of the equation. 8z2 + -8z2 = -9 + 8z2 + -8z2 Combine like terms: 8z2 + -8z2 = 0 0 = -9 + 8z2 + -8z2 Combine like terms: 8z2 + -8z2 = 0 0 = -9 + 0 0 = -9 Solving 0 = -9 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.
