Simplifying x2 + 10x + 99 = 0 Reorder the terms: 99 + 10x + x2 = 0 Solving 99 + 10x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-99' to each side of the equation. 99 + 10x + -99 + x2 = 0 + -99 Reorder the terms: 99 + -99 + 10x + x2 = 0 + -99 Combine like terms: 99 + -99 = 0 0 + 10x + x2 = 0 + -99 10x + x2 = 0 + -99 Combine like terms: 0 + -99 = -99 10x + x2 = -99 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 = -99 + 25 Reorder the terms: 25 + 10x + x2 = -99 + 25 Combine like terms: -99 + 25 = -74 25 + 10x + x2 = -74 Factor a perfect square on the left side: (x + 5)(x + 5) = -74 Can't calculate square root of the right side. The solution to this equation could not be determined.
