Simplifying x2 + 10x + 30000 = 0 Reorder the terms: 30000 + 10x + x2 = 0 Solving 30000 + 10x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-30000' to each side of the equation. 30000 + 10x + -30000 + x2 = 0 + -30000 Reorder the terms: 30000 + -30000 + 10x + x2 = 0 + -30000 Combine like terms: 30000 + -30000 = 0 0 + 10x + x2 = 0 + -30000 10x + x2 = 0 + -30000 Combine like terms: 0 + -30000 = -30000 10x + x2 = -30000 The x term is 10x. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10x + 25 + x2 = -30000 + 25 Reorder the terms: 25 + 10x + x2 = -30000 + 25 Combine like terms: -30000 + 25 = -29975 25 + 10x + x2 = -29975 Factor a perfect square on the left side: (x + 5)(x + 5) = -29975 Can't calculate square root of the right side. The solution to this equation could not be determined.
