Simplifying -5x2 + 5x + -9 = 0 Reorder the terms: -9 + 5x + -5x2 = 0 Solving -9 + 5x + -5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. 1.8 + -1x + x2 = 0 Move the constant term to the right: Add '-1.8' to each side of the equation. 1.8 + -1x + -1.8 + x2 = 0 + -1.8 Reorder the terms: 1.8 + -1.8 + -1x + x2 = 0 + -1.8 Combine like terms: 1.8 + -1.8 = 0.0 0.0 + -1x + x2 = 0 + -1.8 -1x + x2 = 0 + -1.8 Combine like terms: 0 + -1.8 = -1.8 -1x + x2 = -1.8 The x term is -1x. 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 = -1.8 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -1.8 + 0.25 Combine like terms: -1.8 + 0.25 = -1.55 0.25 + -1x + x2 = -1.55 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = -1.55 Can't calculate square root of the right side. The solution to this equation could not be determined.
