Simplifying m2 + -4m + -4 = 5 Reorder the terms: -4 + -4m + m2 = 5 Solving -4 + -4m + m2 = 5 Solving for variable 'm'. Reorder the terms: -4 + -5 + -4m + m2 = 5 + -5 Combine like terms: -4 + -5 = -9 -9 + -4m + m2 = 5 + -5 Combine like terms: 5 + -5 = 0 -9 + -4m + m2 = 0 Begin completing the square. Move the constant term to the right: Add '9' to each side of the equation. -9 + -4m + 9 + m2 = 0 + 9 Reorder the terms: -9 + 9 + -4m + m2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -4m + m2 = 0 + 9 -4m + m2 = 0 + 9 Combine like terms: 0 + 9 = 9 -4m + m2 = 9 The m term is -4m. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4m + 4 + m2 = 9 + 4 Reorder the terms: 4 + -4m + m2 = 9 + 4 Combine like terms: 9 + 4 = 13 4 + -4m + m2 = 13 Factor a perfect square on the left side: (m + -2)(m + -2) = 13 Calculate the square root of the right side: 3.605551275 Break this problem into two subproblems by setting (m + -2) equal to 3.605551275 and -3.605551275.Subproblem 1
m + -2 = 3.605551275 Simplifying m + -2 = 3.605551275 Reorder the terms: -2 + m = 3.605551275 Solving -2 + m = 3.605551275 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + m = 3.605551275 + 2 Combine like terms: -2 + 2 = 0 0 + m = 3.605551275 + 2 m = 3.605551275 + 2 Combine like terms: 3.605551275 + 2 = 5.605551275 m = 5.605551275 Simplifying m = 5.605551275Subproblem 2
m + -2 = -3.605551275 Simplifying m + -2 = -3.605551275 Reorder the terms: -2 + m = -3.605551275 Solving -2 + m = -3.605551275 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + m = -3.605551275 + 2 Combine like terms: -2 + 2 = 0 0 + m = -3.605551275 + 2 m = -3.605551275 + 2 Combine like terms: -3.605551275 + 2 = -1.605551275 m = -1.605551275 Simplifying m = -1.605551275Solution
