Simplifying 4x2 + 21x + 67 = 0 Reorder the terms: 67 + 21x + 4x2 = 0 Solving 67 + 21x + 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'. 16.75 + 5.25x + x2 = 0 Move the constant term to the right: Add '-16.75' to each side of the equation. 16.75 + 5.25x + -16.75 + x2 = 0 + -16.75 Reorder the terms: 16.75 + -16.75 + 5.25x + x2 = 0 + -16.75 Combine like terms: 16.75 + -16.75 = 0.00 0.00 + 5.25x + x2 = 0 + -16.75 5.25x + x2 = 0 + -16.75 Combine like terms: 0 + -16.75 = -16.75 5.25x + x2 = -16.75 The x term is 5.25x. Take half its coefficient (2.625). Square it (6.890625) and add it to both sides. Add '6.890625' to each side of the equation. 5.25x + 6.890625 + x2 = -16.75 + 6.890625 Reorder the terms: 6.890625 + 5.25x + x2 = -16.75 + 6.890625 Combine like terms: -16.75 + 6.890625 = -9.859375 6.890625 + 5.25x + x2 = -9.859375 Factor a perfect square on the left side: (x + 2.625)(x + 2.625) = -9.859375 Can't calculate square root of the right side. The solution to this equation could not be determined.
