Simplifying 5x2 + -22x + 124 = 0 Reorder the terms: 124 + -22x + 5x2 = 0 Solving 124 + -22x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 24.8 + -4.4x + x2 = 0 Move the constant term to the right: Add '-24.8' to each side of the equation. 24.8 + -4.4x + -24.8 + x2 = 0 + -24.8 Reorder the terms: 24.8 + -24.8 + -4.4x + x2 = 0 + -24.8 Combine like terms: 24.8 + -24.8 = 0.0 0.0 + -4.4x + x2 = 0 + -24.8 -4.4x + x2 = 0 + -24.8 Combine like terms: 0 + -24.8 = -24.8 -4.4x + x2 = -24.8 The x term is -4.4x. Take half its coefficient (-2.2). Square it (4.84) and add it to both sides. Add '4.84' to each side of the equation. -4.4x + 4.84 + x2 = -24.8 + 4.84 Reorder the terms: 4.84 + -4.4x + x2 = -24.8 + 4.84 Combine like terms: -24.8 + 4.84 = -19.96 4.84 + -4.4x + x2 = -19.96 Factor a perfect square on the left side: (x + -2.2)(x + -2.2) = -19.96 Can't calculate square root of the right side. The solution to this equation could not be determined.
