Simplifying 0.2x2 + -132x + 28748 = 0 Reorder the terms: 28748 + -132x + 0.2x2 = 0 Solving 28748 + -132x + 0.2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.2 the coefficient of the squared term: Divide each side by '0.2'. 143740 + -660x + x2 = 0 Move the constant term to the right: Add '-143740' to each side of the equation. 143740 + -660x + -143740 + x2 = 0 + -143740 Reorder the terms: 143740 + -143740 + -660x + x2 = 0 + -143740 Combine like terms: 143740 + -143740 = 0 0 + -660x + x2 = 0 + -143740 -660x + x2 = 0 + -143740 Combine like terms: 0 + -143740 = -143740 -660x + x2 = -143740 The x term is -660x. Take half its coefficient (-330). Square it (108900) and add it to both sides. Add '108900' to each side of the equation. -660x + 108900 + x2 = -143740 + 108900 Reorder the terms: 108900 + -660x + x2 = -143740 + 108900 Combine like terms: -143740 + 108900 = -34840 108900 + -660x + x2 = -34840 Factor a perfect square on the left side: (x + -330)(x + -330) = -34840 Can't calculate square root of the right side. The solution to this equation could not be determined.
