Simplifying 2x2 + -10.2x + 16 = 0 Reorder the terms: 16 + -10.2x + 2x2 = 0 Solving 16 + -10.2x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 8 + -5.1x + x2 = 0 Move the constant term to the right: Add '-8' to each side of the equation. 8 + -5.1x + -8 + x2 = 0 + -8 Reorder the terms: 8 + -8 + -5.1x + x2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -5.1x + x2 = 0 + -8 -5.1x + x2 = 0 + -8 Combine like terms: 0 + -8 = -8 -5.1x + x2 = -8 The x term is -5.1x. Take half its coefficient (-2.55). Square it (6.5025) and add it to both sides. Add '6.5025' to each side of the equation. -5.1x + 6.5025 + x2 = -8 + 6.5025 Reorder the terms: 6.5025 + -5.1x + x2 = -8 + 6.5025 Combine like terms: -8 + 6.5025 = -1.4975 6.5025 + -5.1x + x2 = -1.4975 Factor a perfect square on the left side: (x + -2.55)(x + -2.55) = -1.4975 Can't calculate square root of the right side. The solution to this equation could not be determined.
