Simplifying 2x2 + -4x = -5 Reorder the terms: -4x + 2x2 = -5 Solving -4x + 2x2 = -5 Solving for variable 'x'. Reorder the terms: 5 + -4x + 2x2 = -5 + 5 Combine like terms: -5 + 5 = 0 5 + -4x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 2.5 + -2x + x2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + -2x + -2.5 + x2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + -2x + x2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + -2x + x2 = 0 + -2.5 -2x + x2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 -2x + x2 = -2.5 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = -2.5 + 1 Reorder the terms: 1 + -2x + x2 = -2.5 + 1 Combine like terms: -2.5 + 1 = -1.5 1 + -2x + x2 = -1.5 Factor a perfect square on the left side: (x + -1)(x + -1) = -1.5 Can't calculate square root of the right side. The solution to this equation could not be determined.
