Simplifying x2 + -200x + 480000 = 0 Reorder the terms: 480000 + -200x + x2 = 0 Solving 480000 + -200x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-480000' to each side of the equation. 480000 + -200x + -480000 + x2 = 0 + -480000 Reorder the terms: 480000 + -480000 + -200x + x2 = 0 + -480000 Combine like terms: 480000 + -480000 = 0 0 + -200x + x2 = 0 + -480000 -200x + x2 = 0 + -480000 Combine like terms: 0 + -480000 = -480000 -200x + x2 = -480000 The x term is -200x. Take half its coefficient (-100). Square it (10000) and add it to both sides. Add '10000' to each side of the equation. -200x + 10000 + x2 = -480000 + 10000 Reorder the terms: 10000 + -200x + x2 = -480000 + 10000 Combine like terms: -480000 + 10000 = -470000 10000 + -200x + x2 = -470000 Factor a perfect square on the left side: (x + -100)(x + -100) = -470000 Can't calculate square root of the right side. The solution to this equation could not be determined.
