Simplifying -1x2 + 19x + -118 = 0 Reorder the terms: -118 + 19x + -1x2 = 0 Solving -118 + 19x + -1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 118 + -19x + x2 = 0 Move the constant term to the right: Add '-118' to each side of the equation. 118 + -19x + -118 + x2 = 0 + -118 Reorder the terms: 118 + -118 + -19x + x2 = 0 + -118 Combine like terms: 118 + -118 = 0 0 + -19x + x2 = 0 + -118 -19x + x2 = 0 + -118 Combine like terms: 0 + -118 = -118 -19x + x2 = -118 The x term is -19x. Take half its coefficient (-9.5). Square it (90.25) and add it to both sides. Add '90.25' to each side of the equation. -19x + 90.25 + x2 = -118 + 90.25 Reorder the terms: 90.25 + -19x + x2 = -118 + 90.25 Combine like terms: -118 + 90.25 = -27.75 90.25 + -19x + x2 = -27.75 Factor a perfect square on the left side: (x + -9.5)(x + -9.5) = -27.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
