Simplifying 4x2 + -27x + 405 = 0 Reorder the terms: 405 + -27x + 4x2 = 0 Solving 405 + -27x + 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'. 101.25 + -6.75x + x2 = 0 Move the constant term to the right: Add '-101.25' to each side of the equation. 101.25 + -6.75x + -101.25 + x2 = 0 + -101.25 Reorder the terms: 101.25 + -101.25 + -6.75x + x2 = 0 + -101.25 Combine like terms: 101.25 + -101.25 = 0.00 0.00 + -6.75x + x2 = 0 + -101.25 -6.75x + x2 = 0 + -101.25 Combine like terms: 0 + -101.25 = -101.25 -6.75x + x2 = -101.25 The x term is -6.75x. Take half its coefficient (-3.375). Square it (11.390625) and add it to both sides. Add '11.390625' to each side of the equation. -6.75x + 11.390625 + x2 = -101.25 + 11.390625 Reorder the terms: 11.390625 + -6.75x + x2 = -101.25 + 11.390625 Combine like terms: -101.25 + 11.390625 = -89.859375 11.390625 + -6.75x + x2 = -89.859375 Factor a perfect square on the left side: (x + -3.375)(x + -3.375) = -89.859375 Can't calculate square root of the right side. The solution to this equation could not be determined.
