Simplifying 4x2 + 18x + 189 = 0 Reorder the terms: 189 + 18x + 4x2 = 0 Solving 189 + 18x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 47.25 + 4.5x + x2 = 0 Move the constant term to the right: Add '-47.25' to each side of the equation. 47.25 + 4.5x + -47.25 + x2 = 0 + -47.25 Reorder the terms: 47.25 + -47.25 + 4.5x + x2 = 0 + -47.25 Combine like terms: 47.25 + -47.25 = 0.00 0.00 + 4.5x + x2 = 0 + -47.25 4.5x + x2 = 0 + -47.25 Combine like terms: 0 + -47.25 = -47.25 4.5x + x2 = -47.25 The x term is 4.5x. Take half its coefficient (2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. 4.5x + 5.0625 + x2 = -47.25 + 5.0625 Reorder the terms: 5.0625 + 4.5x + x2 = -47.25 + 5.0625 Combine like terms: -47.25 + 5.0625 = -42.1875 5.0625 + 4.5x + x2 = -42.1875 Factor a perfect square on the left side: (x + 2.25)(x + 2.25) = -42.1875 Can't calculate square root of the right side. The solution to this equation could not be determined.
