Simplifying 0.5x2 + 4x + 9 = 0 Reorder the terms: 9 + 4x + 0.5x2 = 0 Solving 9 + 4x + 0.5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.5 the coefficient of the squared term: Divide each side by '0.5'. 18 + 8x + x2 = 0 Move the constant term to the right: Add '-18' to each side of the equation. 18 + 8x + -18 + x2 = 0 + -18 Reorder the terms: 18 + -18 + 8x + x2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + 8x + x2 = 0 + -18 8x + x2 = 0 + -18 Combine like terms: 0 + -18 = -18 8x + x2 = -18 The x term is 8x. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8x + 16 + x2 = -18 + 16 Reorder the terms: 16 + 8x + x2 = -18 + 16 Combine like terms: -18 + 16 = -2 16 + 8x + x2 = -2 Factor a perfect square on the left side: (x + 4)(x + 4) = -2 Can't calculate square root of the right side. The solution to this equation could not be determined.
