Simplifying 12x2 + 21x + 13 = 0 Reorder the terms: 13 + 21x + 12x2 = 0 Solving 13 + 21x + 12x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 12 the coefficient of the squared term: Divide each side by '12'. 1.083333333 + 1.75x + x2 = 0 Move the constant term to the right: Add '-1.083333333' to each side of the equation. 1.083333333 + 1.75x + -1.083333333 + x2 = 0 + -1.083333333 Reorder the terms: 1.083333333 + -1.083333333 + 1.75x + x2 = 0 + -1.083333333 Combine like terms: 1.083333333 + -1.083333333 = 0.000000000 0.000000000 + 1.75x + x2 = 0 + -1.083333333 1.75x + x2 = 0 + -1.083333333 Combine like terms: 0 + -1.083333333 = -1.083333333 1.75x + x2 = -1.083333333 The x term is 1.75x. Take half its coefficient (0.875). Square it (0.765625) and add it to both sides. Add '0.765625' to each side of the equation. 1.75x + 0.765625 + x2 = -1.083333333 + 0.765625 Reorder the terms: 0.765625 + 1.75x + x2 = -1.083333333 + 0.765625 Combine like terms: -1.083333333 + 0.765625 = -0.317708333 0.765625 + 1.75x + x2 = -0.317708333 Factor a perfect square on the left side: (x + 0.875)(x + 0.875) = -0.317708333 Can't calculate square root of the right side. The solution to this equation could not be determined.
