Simplifying (x * x) + 9 = -1[(x * x) + 9] Multiply x * x (x2) + 9 = -1[(x * x) + 9] x2 + 9 = -1[(x * x) + 9] Reorder the terms: 9 + x2 = -1[(x * x) + 9] Multiply x * x 9 + x2 = -1[(x2) + 9] 9 + x2 = -1[x2 + 9] Reorder the terms: 9 + x2 = -1[9 + x2] 9 + x2 = [9 * -1 + x2 * -1] 9 + x2 = [-9 + -1x2] Solving 9 + x2 = -9 + -1x2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add 'x2' to each side of the equation. 9 + x2 + x2 = -9 + -1x2 + x2 Combine like terms: x2 + x2 = 2x2 9 + 2x2 = -9 + -1x2 + x2 Combine like terms: -1x2 + x2 = 0 9 + 2x2 = -9 + 0 9 + 2x2 = -9 Add '-9' to each side of the equation. 9 + -9 + 2x2 = -9 + -9 Combine like terms: 9 + -9 = 0 0 + 2x2 = -9 + -9 2x2 = -9 + -9 Combine like terms: -9 + -9 = -18 2x2 = -18 Divide each side by '2'. x2 = -9 Simplifying x2 = -9 Reorder the terms: 9 + x2 = -9 + 9 Combine like terms: -9 + 9 = 0 9 + x2 = 0 The solution to this equation could not be determined.
