Simplifying 0 = 3x2 + 30x + 117 Reorder the terms: 0 = 117 + 30x + 3x2 Solving 0 = 117 + 30x + 3x2 Solving for variable 'x'. Combine like terms: 0 + -117 = -117 -117 + -30x + -3x2 = 117 + 30x + 3x2 + -117 + -30x + -3x2 Reorder the terms: -117 + -30x + -3x2 = 117 + -117 + 30x + -30x + 3x2 + -3x2 Combine like terms: 117 + -117 = 0 -117 + -30x + -3x2 = 0 + 30x + -30x + 3x2 + -3x2 -117 + -30x + -3x2 = 30x + -30x + 3x2 + -3x2 Combine like terms: 30x + -30x = 0 -117 + -30x + -3x2 = 0 + 3x2 + -3x2 -117 + -30x + -3x2 = 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 -117 + -30x + -3x2 = 0 Factor out the Greatest Common Factor (GCF), '-3'. -3(39 + 10x + x2) = 0 Ignore the factor -3.Subproblem 1
Set the factor '(39 + 10x + x2)' equal to zero and attempt to solve: Simplifying 39 + 10x + x2 = 0 Solving 39 + 10x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-39' to each side of the equation. 39 + 10x + -39 + x2 = 0 + -39 Reorder the terms: 39 + -39 + 10x + x2 = 0 + -39 Combine like terms: 39 + -39 = 0 0 + 10x + x2 = 0 + -39 10x + x2 = 0 + -39 Combine like terms: 0 + -39 = -39 10x + x2 = -39 The x term is 10x. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10x + 25 + x2 = -39 + 25 Reorder the terms: 25 + 10x + x2 = -39 + 25 Combine like terms: -39 + 25 = -14 25 + 10x + x2 = -14 Factor a perfect square on the left side: (x + 5)(x + 5) = -14 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
