Simplifying x2 + 45 = -12x Reorder the terms: 45 + x2 = -12x Solving 45 + x2 = -12x Solving for variable 'x'. Reorder the terms: 45 + 12x + x2 = -12x + 12x Combine like terms: -12x + 12x = 0 45 + 12x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-45' to each side of the equation. 45 + 12x + -45 + x2 = 0 + -45 Reorder the terms: 45 + -45 + 12x + x2 = 0 + -45 Combine like terms: 45 + -45 = 0 0 + 12x + x2 = 0 + -45 12x + x2 = 0 + -45 Combine like terms: 0 + -45 = -45 12x + x2 = -45 The x term is 12x. Take half its coefficient (6). Square it (36) and add it to both sides. Add '36' to each side of the equation. 12x + 36 + x2 = -45 + 36 Reorder the terms: 36 + 12x + x2 = -45 + 36 Combine like terms: -45 + 36 = -9 36 + 12x + x2 = -9 Factor a perfect square on the left side: (x + 6)(x + 6) = -9 Can't calculate square root of the right side. The solution to this equation could not be determined.
