Simplifying 4 + x(5 + -1x) = 18 4 + (5 * x + -1x * x) = 18 4 + (5x + -1x2) = 18 Solving 4 + 5x + -1x2 = 18 Solving for variable 'x'. Reorder the terms: 4 + -18 + 5x + -1x2 = 18 + -18 Combine like terms: 4 + -18 = -14 -14 + 5x + -1x2 = 18 + -18 Combine like terms: 18 + -18 = 0 -14 + 5x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 14 + -5x + x2 = 0 Move the constant term to the right: Add '-14' to each side of the equation. 14 + -5x + -14 + x2 = 0 + -14 Reorder the terms: 14 + -14 + -5x + x2 = 0 + -14 Combine like terms: 14 + -14 = 0 0 + -5x + x2 = 0 + -14 -5x + x2 = 0 + -14 Combine like terms: 0 + -14 = -14 -5x + x2 = -14 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -14 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -14 + 6.25 Combine like terms: -14 + 6.25 = -7.75 6.25 + -5x + x2 = -7.75 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = -7.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
