Simplifying 2x2 + 4x = -15 Reorder the terms: 4x + 2x2 = -15 Solving 4x + 2x2 = -15 Solving for variable 'x'. Reorder the terms: 15 + 4x + 2x2 = -15 + 15 Combine like terms: -15 + 15 = 0 15 + 4x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 7.5 + 2x + x2 = 0 Move the constant term to the right: Add '-7.5' to each side of the equation. 7.5 + 2x + -7.5 + x2 = 0 + -7.5 Reorder the terms: 7.5 + -7.5 + 2x + x2 = 0 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + 2x + x2 = 0 + -7.5 2x + x2 = 0 + -7.5 Combine like terms: 0 + -7.5 = -7.5 2x + x2 = -7.5 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 = -7.5 + 1 Reorder the terms: 1 + 2x + x2 = -7.5 + 1 Combine like terms: -7.5 + 1 = -6.5 1 + 2x + x2 = -6.5 Factor a perfect square on the left side: (x + 1)(x + 1) = -6.5 Can't calculate square root of the right side. The solution to this equation could not be determined.
