Simplifying 2x2 + -9x = -11 Reorder the terms: -9x + 2x2 = -11 Solving -9x + 2x2 = -11 Solving for variable 'x'. Reorder the terms: 11 + -9x + 2x2 = -11 + 11 Combine like terms: -11 + 11 = 0 11 + -9x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 5.5 + -4.5x + x2 = 0 Move the constant term to the right: Add '-5.5' to each side of the equation. 5.5 + -4.5x + -5.5 + x2 = 0 + -5.5 Reorder the terms: 5.5 + -5.5 + -4.5x + x2 = 0 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + -4.5x + x2 = 0 + -5.5 -4.5x + x2 = 0 + -5.5 Combine like terms: 0 + -5.5 = -5.5 -4.5x + x2 = -5.5 The x term is -4.5x. Take half its coefficient (-2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. -4.5x + 5.0625 + x2 = -5.5 + 5.0625 Reorder the terms: 5.0625 + -4.5x + x2 = -5.5 + 5.0625 Combine like terms: -5.5 + 5.0625 = -0.4375 5.0625 + -4.5x + x2 = -0.4375 Factor a perfect square on the left side: (x + -2.25)(x + -2.25) = -0.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
