Simplifying x2 + 40x + 500 = 0 Reorder the terms: 500 + 40x + x2 = 0 Solving 500 + 40x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-500' to each side of the equation. 500 + 40x + -500 + x2 = 0 + -500 Reorder the terms: 500 + -500 + 40x + x2 = 0 + -500 Combine like terms: 500 + -500 = 0 0 + 40x + x2 = 0 + -500 40x + x2 = 0 + -500 Combine like terms: 0 + -500 = -500 40x + x2 = -500 The x term is 40x. Take half its coefficient (20). Square it (400) and add it to both sides. Add '400' to each side of the equation. 40x + 400 + x2 = -500 + 400 Reorder the terms: 400 + 40x + x2 = -500 + 400 Combine like terms: -500 + 400 = -100 400 + 40x + x2 = -100 Factor a perfect square on the left side: (x + 20)(x + 20) = -100 Can't calculate square root of the right side. The solution to this equation could not be determined.
