Simplifying x2 + 30x + 54 = 0 Reorder the terms: 54 + 30x + x2 = 0 Solving 54 + 30x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-54' to each side of the equation. 54 + 30x + -54 + x2 = 0 + -54 Reorder the terms: 54 + -54 + 30x + x2 = 0 + -54 Combine like terms: 54 + -54 = 0 0 + 30x + x2 = 0 + -54 30x + x2 = 0 + -54 Combine like terms: 0 + -54 = -54 30x + x2 = -54 The x term is 30x. Take half its coefficient (15). Square it (225) and add it to both sides. Add '225' to each side of the equation. 30x + 225 + x2 = -54 + 225 Reorder the terms: 225 + 30x + x2 = -54 + 225 Combine like terms: -54 + 225 = 171 225 + 30x + x2 = 171 Factor a perfect square on the left side: (x + 15)(x + 15) = 171 Calculate the square root of the right side: 13.076696831 Break this problem into two subproblems by setting (x + 15) equal to 13.076696831 and -13.076696831.Subproblem 1
x + 15 = 13.076696831 Simplifying x + 15 = 13.076696831 Reorder the terms: 15 + x = 13.076696831 Solving 15 + x = 13.076696831 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -15 + x = 13.076696831 + -15 Combine like terms: 15 + -15 = 0 0 + x = 13.076696831 + -15 x = 13.076696831 + -15 Combine like terms: 13.076696831 + -15 = -1.923303169 x = -1.923303169 Simplifying x = -1.923303169Subproblem 2
x + 15 = -13.076696831 Simplifying x + 15 = -13.076696831 Reorder the terms: 15 + x = -13.076696831 Solving 15 + x = -13.076696831 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -15 + x = -13.076696831 + -15 Combine like terms: 15 + -15 = 0 0 + x = -13.076696831 + -15 x = -13.076696831 + -15 Combine like terms: -13.076696831 + -15 = -28.076696831 x = -28.076696831 Simplifying x = -28.076696831Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.923303169, -28.076696831}
