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.
