Simplifying -2x2 + 5x + -45 = 0 Reorder the terms: -45 + 5x + -2x2 = 0 Solving -45 + 5x + -2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 22.5 + -2.5x + x2 = 0 Move the constant term to the right: Add '-22.5' to each side of the equation. 22.5 + -2.5x + -22.5 + x2 = 0 + -22.5 Reorder the terms: 22.5 + -22.5 + -2.5x + x2 = 0 + -22.5 Combine like terms: 22.5 + -22.5 = 0.0 0.0 + -2.5x + x2 = 0 + -22.5 -2.5x + x2 = 0 + -22.5 Combine like terms: 0 + -22.5 = -22.5 -2.5x + x2 = -22.5 The x term is -2.5x. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5x + 1.5625 + x2 = -22.5 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = -22.5 + 1.5625 Combine like terms: -22.5 + 1.5625 = -20.9375 1.5625 + -2.5x + x2 = -20.9375 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = -20.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
