Simplifying x2 + -10x + 430 = 0 Reorder the terms: 430 + -10x + x2 = 0 Solving 430 + -10x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-430' to each side of the equation. 430 + -10x + -430 + x2 = 0 + -430 Reorder the terms: 430 + -430 + -10x + x2 = 0 + -430 Combine like terms: 430 + -430 = 0 0 + -10x + x2 = 0 + -430 -10x + x2 = 0 + -430 Combine like terms: 0 + -430 = -430 -10x + x2 = -430 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 = -430 + 25 Reorder the terms: 25 + -10x + x2 = -430 + 25 Combine like terms: -430 + 25 = -405 25 + -10x + x2 = -405 Factor a perfect square on the left side: (x + -5)(x + -5) = -405 Can't calculate square root of the right side. The solution to this equation could not be determined.
