Simplifying 3x2 + -18x + 40 = 0 Reorder the terms: 40 + -18x + 3x2 = 0 Solving 40 + -18x + 3x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 13.33333333 + -6x + x2 = 0 Move the constant term to the right: Add '-13.33333333' to each side of the equation. 13.33333333 + -6x + -13.33333333 + x2 = 0 + -13.33333333 Reorder the terms: 13.33333333 + -13.33333333 + -6x + x2 = 0 + -13.33333333 Combine like terms: 13.33333333 + -13.33333333 = 0.00000000 0.00000000 + -6x + x2 = 0 + -13.33333333 -6x + x2 = 0 + -13.33333333 Combine like terms: 0 + -13.33333333 = -13.33333333 -6x + x2 = -13.33333333 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 = -13.33333333 + 9 Reorder the terms: 9 + -6x + x2 = -13.33333333 + 9 Combine like terms: -13.33333333 + 9 = -4.33333333 9 + -6x + x2 = -4.33333333 Factor a perfect square on the left side: (x + -3)(x + -3) = -4.33333333 Can't calculate square root of the right side. The solution to this equation could not be determined.
