Simplifying -2x2 + 6x + -4 = 4.5 Reorder the terms: -4 + 6x + -2x2 = 4.5 Solving -4 + 6x + -2x2 = 4.5 Solving for variable 'x'. Reorder the terms: -4 + -4.5 + 6x + -2x2 = 4.5 + -4.5 Combine like terms: -4 + -4.5 = -8.5 -8.5 + 6x + -2x2 = 4.5 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 -8.5 + 6x + -2x2 = 0.0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 4.25 + -3x + x2 = 0.0 Move the constant term to the right: Add '-4.25' to each side of the equation. 4.25 + -3x + -4.25 + x2 = 0.0 + -4.25 Reorder the terms: 4.25 + -4.25 + -3x + x2 = 0.0 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + -3x + x2 = 0.0 + -4.25 -3x + x2 = 0.0 + -4.25 Combine like terms: 0.0 + -4.25 = -4.25 -3x + x2 = -4.25 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = -4.25 + 2.25 Reorder the terms: 2.25 + -3x + x2 = -4.25 + 2.25 Combine like terms: -4.25 + 2.25 = -2 2.25 + -3x + x2 = -2 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = -2 Can't calculate square root of the right side. The solution to this equation could not be determined.
