Simplifying 4x2 + 11x + 34 = 0 Reorder the terms: 34 + 11x + 4x2 = 0 Solving 34 + 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'. 8.5 + 2.75x + x2 = 0 Move the constant term to the right: Add '-8.5' to each side of the equation. 8.5 + 2.75x + -8.5 + x2 = 0 + -8.5 Reorder the terms: 8.5 + -8.5 + 2.75x + x2 = 0 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + 2.75x + x2 = 0 + -8.5 2.75x + x2 = 0 + -8.5 Combine like terms: 0 + -8.5 = -8.5 2.75x + x2 = -8.5 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 = -8.5 + 1.890625 Reorder the terms: 1.890625 + 2.75x + x2 = -8.5 + 1.890625 Combine like terms: -8.5 + 1.890625 = -6.609375 1.890625 + 2.75x + x2 = -6.609375 Factor a perfect square on the left side: (x + 1.375)(x + 1.375) = -6.609375 Can't calculate square root of the right side. The solution to this equation could not be determined.
