Simplifying 13 = x2 + -6x + 140 Reorder the terms: 13 = 140 + -6x + x2 Solving 13 = 140 + -6x + x2 Solving for variable 'x'. Combine like terms: 13 + -140 = -127 -127 + 6x + -1x2 = 140 + -6x + x2 + -140 + 6x + -1x2 Reorder the terms: -127 + 6x + -1x2 = 140 + -140 + -6x + 6x + x2 + -1x2 Combine like terms: 140 + -140 = 0 -127 + 6x + -1x2 = 0 + -6x + 6x + x2 + -1x2 -127 + 6x + -1x2 = -6x + 6x + x2 + -1x2 Combine like terms: -6x + 6x = 0 -127 + 6x + -1x2 = 0 + x2 + -1x2 -127 + 6x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -127 + 6x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 127 + -6x + x2 = 0 Move the constant term to the right: Add '-127' to each side of the equation. 127 + -6x + -127 + x2 = 0 + -127 Reorder the terms: 127 + -127 + -6x + x2 = 0 + -127 Combine like terms: 127 + -127 = 0 0 + -6x + x2 = 0 + -127 -6x + x2 = 0 + -127 Combine like terms: 0 + -127 = -127 -6x + x2 = -127 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = -127 + 9 Reorder the terms: 9 + -6x + x2 = -127 + 9 Combine like terms: -127 + 9 = -118 9 + -6x + x2 = -118 Factor a perfect square on the left side: (x + -3)(x + -3) = -118 Can't calculate square root of the right side. The solution to this equation could not be determined.
