Simplifying -2x2 + 3x + -8 = 0 Reorder the terms: -8 + 3x + -2x2 = 0 Solving -8 + 3x + -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'. 4 + -1.5x + x2 = 0 Move the constant term to the right: Add '-4' to each side of the equation. 4 + -1.5x + -4 + x2 = 0 + -4 Reorder the terms: 4 + -4 + -1.5x + x2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1.5x + x2 = 0 + -4 -1.5x + x2 = 0 + -4 Combine like terms: 0 + -4 = -4 -1.5x + x2 = -4 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = -4 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = -4 + 0.5625 Combine like terms: -4 + 0.5625 = -3.4375 0.5625 + -1.5x + x2 = -3.4375 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = -3.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
