Simplifying 8x2 + 16x + 87 = 0 Reorder the terms: 87 + 16x + 8x2 = 0 Solving 87 + 16x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 10.875 + 2x + x2 = 0 Move the constant term to the right: Add '-10.875' to each side of the equation. 10.875 + 2x + -10.875 + x2 = 0 + -10.875 Reorder the terms: 10.875 + -10.875 + 2x + x2 = 0 + -10.875 Combine like terms: 10.875 + -10.875 = 0.000 0.000 + 2x + x2 = 0 + -10.875 2x + x2 = 0 + -10.875 Combine like terms: 0 + -10.875 = -10.875 2x + x2 = -10.875 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 = -10.875 + 1 Reorder the terms: 1 + 2x + x2 = -10.875 + 1 Combine like terms: -10.875 + 1 = -9.875 1 + 2x + x2 = -9.875 Factor a perfect square on the left side: (x + 1)(x + 1) = -9.875 Can't calculate square root of the right side. The solution to this equation could not be determined.
