Simplifying 8x2 + -1(-2 + -1) * x + 32 = 0 Combine like terms: -2 + -1 = -3 8x2 + -1(-3) * x + 32 = 0 Multiply -1 * -3 8x2 + 3x + 32 = 0 Reorder the terms: 32 + 3x + 8x2 = 0 Solving 32 + 3x + 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'. 4 + 0.375x + x2 = 0 Move the constant term to the right: Add '-4' to each side of the equation. 4 + 0.375x + -4 + x2 = 0 + -4 Reorder the terms: 4 + -4 + 0.375x + x2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 0.375x + x2 = 0 + -4 0.375x + x2 = 0 + -4 Combine like terms: 0 + -4 = -4 0.375x + x2 = -4 The x term is 0.375x. Take half its coefficient (0.1875). Square it (0.03515625) and add it to both sides. Add '0.03515625' to each side of the equation. 0.375x + 0.03515625 + x2 = -4 + 0.03515625 Reorder the terms: 0.03515625 + 0.375x + x2 = -4 + 0.03515625 Combine like terms: -4 + 0.03515625 = -3.96484375 0.03515625 + 0.375x + x2 = -3.96484375 Factor a perfect square on the left side: (x + 0.1875)(x + 0.1875) = -3.96484375 Can't calculate square root of the right side. The solution to this equation could not be determined.
