Simplifying x2 + 2mx + -1(m + -20) = 0 Reorder the terms: x2 + 2mx + -1(-20 + m) = 0 x2 + 2mx + (-20 * -1 + m * -1) = 0 x2 + 2mx + (20 + -1m) = 0 Reorder the terms: 20 + -1m + 2mx + x2 = 0 Solving 20 + -1m + 2mx + x2 = 0 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -1m + 2mx + -20 + x2 = 0 + -20 Reorder the terms: 20 + -20 + -1m + 2mx + x2 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + -1m + 2mx + x2 = 0 + -20 -1m + 2mx + x2 = 0 + -20 Combine like terms: 0 + -20 = -20 -1m + 2mx + x2 = -20 Add '-1x2' to each side of the equation. -1m + 2mx + x2 + -1x2 = -20 + -1x2 Combine like terms: x2 + -1x2 = 0 -1m + 2mx + 0 = -20 + -1x2 -1m + 2mx = -20 + -1x2 Reorder the terms: 20 + -1m + 2mx + x2 = -20 + -1x2 + 20 + x2 Reorder the terms: 20 + -1m + 2mx + x2 = -20 + 20 + -1x2 + x2 Combine like terms: -20 + 20 = 0 20 + -1m + 2mx + x2 = 0 + -1x2 + x2 20 + -1m + 2mx + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 20 + -1m + 2mx + x2 = 0 The solution to this equation could not be determined.
