Simplifying 9x2 + -4 = -12x + -292 Reorder the terms: -4 + 9x2 = -12x + -292 Reorder the terms: -4 + 9x2 = -292 + -12x Solving -4 + 9x2 = -292 + -12x Solving for variable 'x'. Reorder the terms: -4 + 292 + 12x + 9x2 = -292 + -12x + 292 + 12x Combine like terms: -4 + 292 = 288 288 + 12x + 9x2 = -292 + -12x + 292 + 12x Reorder the terms: 288 + 12x + 9x2 = -292 + 292 + -12x + 12x Combine like terms: -292 + 292 = 0 288 + 12x + 9x2 = 0 + -12x + 12x 288 + 12x + 9x2 = -12x + 12x Combine like terms: -12x + 12x = 0 288 + 12x + 9x2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(96 + 4x + 3x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(96 + 4x + 3x2)' equal to zero and attempt to solve: Simplifying 96 + 4x + 3x2 = 0 Solving 96 + 4x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 32 + 1.333333333x + x2 = 0 Move the constant term to the right: Add '-32' to each side of the equation. 32 + 1.333333333x + -32 + x2 = 0 + -32 Reorder the terms: 32 + -32 + 1.333333333x + x2 = 0 + -32 Combine like terms: 32 + -32 = 0 0 + 1.333333333x + x2 = 0 + -32 1.333333333x + x2 = 0 + -32 Combine like terms: 0 + -32 = -32 1.333333333x + x2 = -32 The x term is 1.333333333x. Take half its coefficient (0.6666666665). Square it (0.4444444442) and add it to both sides. Add '0.4444444442' to each side of the equation. 1.333333333x + 0.4444444442 + x2 = -32 + 0.4444444442 Reorder the terms: 0.4444444442 + 1.333333333x + x2 = -32 + 0.4444444442 Combine like terms: -32 + 0.4444444442 = -31.5555555558 0.4444444442 + 1.333333333x + x2 = -31.5555555558 Factor a perfect square on the left side: (x + 0.6666666665)(x + 0.6666666665) = -31.5555555558 Can't calculate square root of the right side.
