Simplifying 4x2 + -11x + 18 = 0 Reorder the terms: 18 + -11x + 4x2 = 0 Solving 18 + -11x + 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'. 4.5 + -2.75x + x2 = 0 Move the constant term to the right: Add '-4.5' to each side of the equation. 4.5 + -2.75x + -4.5 + x2 = 0 + -4.5 Reorder the terms: 4.5 + -4.5 + -2.75x + x2 = 0 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + -2.75x + x2 = 0 + -4.5 -2.75x + x2 = 0 + -4.5 Combine like terms: 0 + -4.5 = -4.5 -2.75x + x2 = -4.5 The x term is -2.75x. Take half its coefficient (-1.375). Square it (1.890625) and add it to both sides. Add '1.890625' to each side of the equation. -2.75x + 1.890625 + x2 = -4.5 + 1.890625 Reorder the terms: 1.890625 + -2.75x + x2 = -4.5 + 1.890625 Combine like terms: -4.5 + 1.890625 = -2.609375 1.890625 + -2.75x + x2 = -2.609375 Factor a perfect square on the left side: (x + -1.375)(x + -1.375) = -2.609375 Can't calculate square root of the right side. The solution to this equation could not be determined.
