Simplifying 2x2 + 9 = -4x Reorder the terms: 9 + 2x2 = -4x Solving 9 + 2x2 = -4x Solving for variable 'x'. Reorder the terms: 9 + 4x + 2x2 = -4x + 4x Combine like terms: -4x + 4x = 0 9 + 4x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 4.5 + 2x + x2 = 0 Move the constant term to the right: Add '-4.5' to each side of the equation. 4.5 + 2x + -4.5 + x2 = 0 + -4.5 Reorder the terms: 4.5 + -4.5 + 2x + x2 = 0 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + 2x + x2 = 0 + -4.5 2x + x2 = 0 + -4.5 Combine like terms: 0 + -4.5 = -4.5 2x + x2 = -4.5 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 = -4.5 + 1 Reorder the terms: 1 + 2x + x2 = -4.5 + 1 Combine like terms: -4.5 + 1 = -3.5 1 + 2x + x2 = -3.5 Factor a perfect square on the left side: (x + 1)(x + 1) = -3.5 Can't calculate square root of the right side. The solution to this equation could not be determined.
