Simplifying 80x2 + -620x + 1360 = 0 Reorder the terms: 1360 + -620x + 80x2 = 0 Solving 1360 + -620x + 80x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '20'. 20(68 + -31x + 4x2) = 0 Ignore the factor 20.Subproblem 1
Set the factor '(68 + -31x + 4x2)' equal to zero and attempt to solve: Simplifying 68 + -31x + 4x2 = 0 Solving 68 + -31x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 17 + -7.75x + x2 = 0 Move the constant term to the right: Add '-17' to each side of the equation. 17 + -7.75x + -17 + x2 = 0 + -17 Reorder the terms: 17 + -17 + -7.75x + x2 = 0 + -17 Combine like terms: 17 + -17 = 0 0 + -7.75x + x2 = 0 + -17 -7.75x + x2 = 0 + -17 Combine like terms: 0 + -17 = -17 -7.75x + x2 = -17 The x term is -7.75x. Take half its coefficient (-3.875). Square it (15.015625) and add it to both sides. Add '15.015625' to each side of the equation. -7.75x + 15.015625 + x2 = -17 + 15.015625 Reorder the terms: 15.015625 + -7.75x + x2 = -17 + 15.015625 Combine like terms: -17 + 15.015625 = -1.984375 15.015625 + -7.75x + x2 = -1.984375 Factor a perfect square on the left side: (x + -3.875)(x + -3.875) = -1.984375 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.
