Simplifying 4 = x2 + -6x + 31 Reorder the terms: 4 = 31 + -6x + x2 Solving 4 = 31 + -6x + x2 Solving for variable 'x'. Combine like terms: 4 + -31 = -27 -27 + 6x + -1x2 = 31 + -6x + x2 + -31 + 6x + -1x2 Reorder the terms: -27 + 6x + -1x2 = 31 + -31 + -6x + 6x + x2 + -1x2 Combine like terms: 31 + -31 = 0 -27 + 6x + -1x2 = 0 + -6x + 6x + x2 + -1x2 -27 + 6x + -1x2 = -6x + 6x + x2 + -1x2 Combine like terms: -6x + 6x = 0 -27 + 6x + -1x2 = 0 + x2 + -1x2 -27 + 6x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -27 + 6x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 27 + -6x + x2 = 0 Move the constant term to the right: Add '-27' to each side of the equation. 27 + -6x + -27 + x2 = 0 + -27 Reorder the terms: 27 + -27 + -6x + x2 = 0 + -27 Combine like terms: 27 + -27 = 0 0 + -6x + x2 = 0 + -27 -6x + x2 = 0 + -27 Combine like terms: 0 + -27 = -27 -6x + x2 = -27 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 = -27 + 9 Reorder the terms: 9 + -6x + x2 = -27 + 9 Combine like terms: -27 + 9 = -18 9 + -6x + x2 = -18 Factor a perfect square on the left side: (x + -3)(x + -3) = -18 Can't calculate square root of the right side. The solution to this equation could not be determined.
