Simplifying -4x2 + 9x + -12 = 0 Reorder the terms: -12 + 9x + -4x2 = 0 Solving -12 + 9x + -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'. 3 + -2.25x + x2 = 0 Move the constant term to the right: Add '-3' to each side of the equation. 3 + -2.25x + -3 + x2 = 0 + -3 Reorder the terms: 3 + -3 + -2.25x + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -2.25x + x2 = 0 + -3 -2.25x + x2 = 0 + -3 Combine like terms: 0 + -3 = -3 -2.25x + x2 = -3 The x term is -2.25x. Take half its coefficient (-1.125). Square it (1.265625) and add it to both sides. Add '1.265625' to each side of the equation. -2.25x + 1.265625 + x2 = -3 + 1.265625 Reorder the terms: 1.265625 + -2.25x + x2 = -3 + 1.265625 Combine like terms: -3 + 1.265625 = -1.734375 1.265625 + -2.25x + x2 = -1.734375 Factor a perfect square on the left side: (x + -1.125)(x + -1.125) = -1.734375 Can't calculate square root of the right side. The solution to this equation could not be determined.
