Simplifying (12 + -1x) * x + -1x = 63 Reorder the terms for easier multiplication: x(12 + -1x) + -1x = 63 (12 * x + -1x * x) + -1x = 63 (12x + -1x2) + -1x = 63 Reorder the terms: 12x + -1x + -1x2 = 63 Combine like terms: 12x + -1x = 11x 11x + -1x2 = 63 Solving 11x + -1x2 = 63 Solving for variable 'x'. Reorder the terms: -63 + 11x + -1x2 = 63 + -63 Combine like terms: 63 + -63 = 0 -63 + 11x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 63 + -11x + x2 = 0 Move the constant term to the right: Add '-63' to each side of the equation. 63 + -11x + -63 + x2 = 0 + -63 Reorder the terms: 63 + -63 + -11x + x2 = 0 + -63 Combine like terms: 63 + -63 = 0 0 + -11x + x2 = 0 + -63 -11x + x2 = 0 + -63 Combine like terms: 0 + -63 = -63 -11x + x2 = -63 The x term is -11x. Take half its coefficient (-5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. -11x + 30.25 + x2 = -63 + 30.25 Reorder the terms: 30.25 + -11x + x2 = -63 + 30.25 Combine like terms: -63 + 30.25 = -32.75 30.25 + -11x + x2 = -32.75 Factor a perfect square on the left side: (x + -5.5)(x + -5.5) = -32.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
