Simplifying 12.5x2 + 5x + 4.5 = 0 Reorder the terms: 4.5 + 5x + 12.5x2 = 0 Solving 4.5 + 5x + 12.5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 12.5 the coefficient of the squared term: Divide each side by '12.5'. 0.36 + 0.4x + x2 = 0 Move the constant term to the right: Add '-0.36' to each side of the equation. 0.36 + 0.4x + -0.36 + x2 = 0 + -0.36 Reorder the terms: 0.36 + -0.36 + 0.4x + x2 = 0 + -0.36 Combine like terms: 0.36 + -0.36 = 0.00 0.00 + 0.4x + x2 = 0 + -0.36 0.4x + x2 = 0 + -0.36 Combine like terms: 0 + -0.36 = -0.36 0.4x + x2 = -0.36 The x term is 0.4x. Take half its coefficient (0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. 0.4x + 0.04 + x2 = -0.36 + 0.04 Reorder the terms: 0.04 + 0.4x + x2 = -0.36 + 0.04 Combine like terms: -0.36 + 0.04 = -0.32 0.04 + 0.4x + x2 = -0.32 Factor a perfect square on the left side: (x + 0.2)(x + 0.2) = -0.32 Can't calculate square root of the right side. The solution to this equation could not be determined.
