Simplifying 7x + -3x2 = 85 + 2x2 + 2x Reorder the terms: 7x + -3x2 = 85 + 2x + 2x2 Solving 7x + -3x2 = 85 + 2x + 2x2 Solving for variable 'x'. Reorder the terms: -85 + 7x + -2x + -3x2 + -2x2 = 85 + 2x + 2x2 + -85 + -2x + -2x2 Combine like terms: 7x + -2x = 5x -85 + 5x + -3x2 + -2x2 = 85 + 2x + 2x2 + -85 + -2x + -2x2 Combine like terms: -3x2 + -2x2 = -5x2 -85 + 5x + -5x2 = 85 + 2x + 2x2 + -85 + -2x + -2x2 Reorder the terms: -85 + 5x + -5x2 = 85 + -85 + 2x + -2x + 2x2 + -2x2 Combine like terms: 85 + -85 = 0 -85 + 5x + -5x2 = 0 + 2x + -2x + 2x2 + -2x2 -85 + 5x + -5x2 = 2x + -2x + 2x2 + -2x2 Combine like terms: 2x + -2x = 0 -85 + 5x + -5x2 = 0 + 2x2 + -2x2 -85 + 5x + -5x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 -85 + 5x + -5x2 = 0 Factor out the Greatest Common Factor (GCF), '5'. 5(-17 + x + -1x2) = 0 Ignore the factor 5.Subproblem 1
Set the factor '(-17 + x + -1x2)' equal to zero and attempt to solve: Simplifying -17 + x + -1x2 = 0 Solving -17 + x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 17 + -1x + x2 = 0 Move the constant term to the right: Add '-17' to each side of the equation. 17 + -1x + -17 + x2 = 0 + -17 Reorder the terms: 17 + -17 + -1x + x2 = 0 + -17 Combine like terms: 17 + -17 = 0 0 + -1x + x2 = 0 + -17 -1x + x2 = 0 + -17 Combine like terms: 0 + -17 = -17 -1x + x2 = -17 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = -17 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -17 + 0.25 Combine like terms: -17 + 0.25 = -16.75 0.25 + -1x + x2 = -16.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -16.75 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.
