Simplifying 0.5x2 + 2.2x = -3.6 Reorder the terms: 2.2x + 0.5x2 = -3.6 Solving 2.2x + 0.5x2 = -3.6 Solving for variable 'x'. Reorder the terms: 3.6 + 2.2x + 0.5x2 = -3.6 + 3.6 Combine like terms: -3.6 + 3.6 = 0.0 3.6 + 2.2x + 0.5x2 = 0.0 Begin completing the square. Divide all terms by 0.5 the coefficient of the squared term: Divide each side by '0.5'. 7.2 + 4.4x + x2 = 0 Move the constant term to the right: Add '-7.2' to each side of the equation. 7.2 + 4.4x + -7.2 + x2 = 0 + -7.2 Reorder the terms: 7.2 + -7.2 + 4.4x + x2 = 0 + -7.2 Combine like terms: 7.2 + -7.2 = 0.0 0.0 + 4.4x + x2 = 0 + -7.2 4.4x + x2 = 0 + -7.2 Combine like terms: 0 + -7.2 = -7.2 4.4x + x2 = -7.2 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 = -7.2 + 4.84 Reorder the terms: 4.84 + 4.4x + x2 = -7.2 + 4.84 Combine like terms: -7.2 + 4.84 = -2.36 4.84 + 4.4x + x2 = -2.36 Factor a perfect square on the left side: (x + 2.2)(x + 2.2) = -2.36 Can't calculate square root of the right side. The solution to this equation could not be determined.
