Simplifying 4x2 + 8x + 31 = 0 Reorder the terms: 31 + 8x + 4x2 = 0 Solving 31 + 8x + 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'. 7.75 + 2x + x2 = 0 Move the constant term to the right: Add '-7.75' to each side of the equation. 7.75 + 2x + -7.75 + x2 = 0 + -7.75 Reorder the terms: 7.75 + -7.75 + 2x + x2 = 0 + -7.75 Combine like terms: 7.75 + -7.75 = 0.00 0.00 + 2x + x2 = 0 + -7.75 2x + x2 = 0 + -7.75 Combine like terms: 0 + -7.75 = -7.75 2x + x2 = -7.75 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = -7.75 + 1 Reorder the terms: 1 + 2x + x2 = -7.75 + 1 Combine like terms: -7.75 + 1 = -6.75 1 + 2x + x2 = -6.75 Factor a perfect square on the left side: (x + 1)(x + 1) = -6.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
