Simplifying 4x2 + -31x + 63 = 0 Reorder the terms: 63 + -31x + 4x2 = 0 Solving 63 + -31x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 15.75 + -7.75x + x2 = 0 Move the constant term to the right: Add '-15.75' to each side of the equation. 15.75 + -7.75x + -15.75 + x2 = 0 + -15.75 Reorder the terms: 15.75 + -15.75 + -7.75x + x2 = 0 + -15.75 Combine like terms: 15.75 + -15.75 = 0.00 0.00 + -7.75x + x2 = 0 + -15.75 -7.75x + x2 = 0 + -15.75 Combine like terms: 0 + -15.75 = -15.75 -7.75x + x2 = -15.75 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 = -15.75 + 15.015625 Reorder the terms: 15.015625 + -7.75x + x2 = -15.75 + 15.015625 Combine like terms: -15.75 + 15.015625 = -0.734375 15.015625 + -7.75x + x2 = -0.734375 Factor a perfect square on the left side: (x + -3.875)(x + -3.875) = -0.734375 Can't calculate square root of the right side. The solution to this equation could not be determined.
