Solve the equation using square roots. m^2+8m+16=45

Simplifying M2 + 8m + 16 = 45 Reorder the terms: 16 + M2 + 8m = 45 Solving 16 + M2 + 8m = 45 Solving for variable 'M'. Move all terms containing M to the left, all other terms to the right. Add '-16' to each side of the equation. 16 + M2 + - 16 + 8m = 45 + - 16 Reorder the terms: 16 + - 16 + M2 + 8m = 45 + - 16 Combine like terms: 16 + - 16 = 0 0 + M2 + 8m = 45 + - 16 M2 + 8m = 45 + - 16 Combine like terms: 45 + - 16 = 29 M2 + 8m = 29 Add '-8m' to each side of the equation. M2 + 8m + - 8m = 29 + - 8m Combine like terms: 8m + - 8m = 0 M2 + 0 = 29 + - 8m M2 = 29 + - 8m Simplifying M2 = 29 + - 8m Reorder the terms: - 29 + M2 + 8m = 29 + - 8m + - 29 + 8m Reorder the terms: - 29 + M2 + 8m = 29 + - 29 + - 8m + 8m Combine like terms: 29 + - 29 = 0 - 29 + M2 + 8m = 0 + - 8m + 8m - 29 + M2 + 8m = - 8m + 8m Combine like terms: - 8m + 8m = 0 - 29 + M2 + 8m = 0 The solution to this equation could not be determined.
