Simplifying 4x2 + -35x + 98 = 0 Reorder the terms: 98 + -35x + 4x2 = 0 Solving 98 + -35x + 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'. 24.5 + -8.75x + x2 = 0 Move the constant term to the right: Add '-24.5' to each side of the equation. 24.5 + -8.75x + -24.5 + x2 = 0 + -24.5 Reorder the terms: 24.5 + -24.5 + -8.75x + x2 = 0 + -24.5 Combine like terms: 24.5 + -24.5 = 0.0 0.0 + -8.75x + x2 = 0 + -24.5 -8.75x + x2 = 0 + -24.5 Combine like terms: 0 + -24.5 = -24.5 -8.75x + x2 = -24.5 The x term is -8.75x. Take half its coefficient (-4.375). Square it (19.140625) and add it to both sides. Add '19.140625' to each side of the equation. -8.75x + 19.140625 + x2 = -24.5 + 19.140625 Reorder the terms: 19.140625 + -8.75x + x2 = -24.5 + 19.140625 Combine like terms: -24.5 + 19.140625 = -5.359375 19.140625 + -8.75x + x2 = -5.359375 Factor a perfect square on the left side: (x + -4.375)(x + -4.375) = -5.359375 Can't calculate square root of the right side. The solution to this equation could not be determined.
