Simplifying -4X2 = -9X + 15 Reorder the terms: -4X2 = 15 + -9X Solving -4X2 = 15 + -9X Solving for variable 'X'. Reorder the terms: -15 + 9X + -4X2 = 15 + -9X + -15 + 9X Reorder the terms: -15 + 9X + -4X2 = 15 + -15 + -9X + 9X Combine like terms: 15 + -15 = 0 -15 + 9X + -4X2 = 0 + -9X + 9X -15 + 9X + -4X2 = -9X + 9X Combine like terms: -9X + 9X = 0 -15 + 9X + -4X2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. 3.75 + -2.25X + X2 = 0 Move the constant term to the right: Add '-3.75' to each side of the equation. 3.75 + -2.25X + -3.75 + X2 = 0 + -3.75 Reorder the terms: 3.75 + -3.75 + -2.25X + X2 = 0 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + -2.25X + X2 = 0 + -3.75 -2.25X + X2 = 0 + -3.75 Combine like terms: 0 + -3.75 = -3.75 -2.25X + X2 = -3.75 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 = -3.75 + 1.265625 Reorder the terms: 1.265625 + -2.25X + X2 = -3.75 + 1.265625 Combine like terms: -3.75 + 1.265625 = -2.484375 1.265625 + -2.25X + X2 = -2.484375 Factor a perfect square on the left side: (X + -1.125)(X + -1.125) = -2.484375 Can't calculate square root of the right side. The solution to this equation could not be determined.
