Simplifying x2 + 3 + 5x + x2 + 12 = 0 Reorder the terms: 3 + 12 + 5x + x2 + x2 = 0 Combine like terms: 3 + 12 = 15 15 + 5x + x2 + x2 = 0 Combine like terms: x2 + x2 = 2x2 15 + 5x + 2x2 = 0 Solving 15 + 5x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 7.5 + 2.5x + x2 = 0 Move the constant term to the right: Add '-7.5' to each side of the equation. 7.5 + 2.5x + -7.5 + x2 = 0 + -7.5 Reorder the terms: 7.5 + -7.5 + 2.5x + x2 = 0 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + 2.5x + x2 = 0 + -7.5 2.5x + x2 = 0 + -7.5 Combine like terms: 0 + -7.5 = -7.5 2.5x + x2 = -7.5 The x term is 2.5x. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5x + 1.5625 + x2 = -7.5 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = -7.5 + 1.5625 Combine like terms: -7.5 + 1.5625 = -5.9375 1.5625 + 2.5x + x2 = -5.9375 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = -5.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
