Simplifying x2 + 32x + 28 = 0 Reorder the terms: 28 + 32x + x2 = 0 Solving 28 + 32x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-28' to each side of the equation. 28 + 32x + -28 + x2 = 0 + -28 Reorder the terms: 28 + -28 + 32x + x2 = 0 + -28 Combine like terms: 28 + -28 = 0 0 + 32x + x2 = 0 + -28 32x + x2 = 0 + -28 Combine like terms: 0 + -28 = -28 32x + x2 = -28 The x term is 32x. Take half its coefficient (16). Square it (256) and add it to both sides. Add '256' to each side of the equation. 32x + 256 + x2 = -28 + 256 Reorder the terms: 256 + 32x + x2 = -28 + 256 Combine like terms: -28 + 256 = 228 256 + 32x + x2 = 228 Factor a perfect square on the left side: (x + 16)(x + 16) = 228 Calculate the square root of the right side: 15.099668871 Break this problem into two subproblems by setting (x + 16) equal to 15.099668871 and -15.099668871.Subproblem 1
x + 16 = 15.099668871 Simplifying x + 16 = 15.099668871 Reorder the terms: 16 + x = 15.099668871 Solving 16 + x = 15.099668871 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-16' to each side of the equation. 16 + -16 + x = 15.099668871 + -16 Combine like terms: 16 + -16 = 0 0 + x = 15.099668871 + -16 x = 15.099668871 + -16 Combine like terms: 15.099668871 + -16 = -0.900331129 x = -0.900331129 Simplifying x = -0.900331129Subproblem 2
x + 16 = -15.099668871 Simplifying x + 16 = -15.099668871 Reorder the terms: 16 + x = -15.099668871 Solving 16 + x = -15.099668871 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-16' to each side of the equation. 16 + -16 + x = -15.099668871 + -16 Combine like terms: 16 + -16 = 0 0 + x = -15.099668871 + -16 x = -15.099668871 + -16 Combine like terms: -15.099668871 + -16 = -31.099668871 x = -31.099668871 Simplifying x = -31.099668871Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.900331129, -31.099668871}
