Simplifying -9x2 + 18x + -11 = 0 Reorder the terms: -11 + 18x + -9x2 = 0 Solving -11 + 18x + -9x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -9 the coefficient of the squared term: Divide each side by '-9'. 1.222222222 + -2x + x2 = 0 Move the constant term to the right: Add '-1.222222222' to each side of the equation. 1.222222222 + -2x + -1.222222222 + x2 = 0 + -1.222222222 Reorder the terms: 1.222222222 + -1.222222222 + -2x + x2 = 0 + -1.222222222 Combine like terms: 1.222222222 + -1.222222222 = 0.000000000 0.000000000 + -2x + x2 = 0 + -1.222222222 -2x + x2 = 0 + -1.222222222 Combine like terms: 0 + -1.222222222 = -1.222222222 -2x + x2 = -1.222222222 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = -1.222222222 + 1 Reorder the terms: 1 + -2x + x2 = -1.222222222 + 1 Combine like terms: -1.222222222 + 1 = -0.222222222 1 + -2x + x2 = -0.222222222 Factor a perfect square on the left side: (x + -1)(x + -1) = -0.222222222 Can't calculate square root of the right side. The solution to this equation could not be determined.
