Simplifying x2 + -10x + 300 = 0 Reorder the terms: 300 + -10x + x2 = 0 Solving 300 + -10x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-300' to each side of the equation. 300 + -10x + -300 + x2 = 0 + -300 Reorder the terms: 300 + -300 + -10x + x2 = 0 + -300 Combine like terms: 300 + -300 = 0 0 + -10x + x2 = 0 + -300 -10x + x2 = 0 + -300 Combine like terms: 0 + -300 = -300 -10x + x2 = -300 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 = -300 + 25 Reorder the terms: 25 + -10x + x2 = -300 + 25 Combine like terms: -300 + 25 = -275 25 + -10x + x2 = -275 Factor a perfect square on the left side: (x + -5)(x + -5) = -275 Can't calculate square root of the right side. The solution to this equation could not be determined.
