Simplifying x2 + -150x + 40000 = 0 Reorder the terms: 40000 + -150x + x2 = 0 Solving 40000 + -150x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-40000' to each side of the equation. 40000 + -150x + -40000 + x2 = 0 + -40000 Reorder the terms: 40000 + -40000 + -150x + x2 = 0 + -40000 Combine like terms: 40000 + -40000 = 0 0 + -150x + x2 = 0 + -40000 -150x + x2 = 0 + -40000 Combine like terms: 0 + -40000 = -40000 -150x + x2 = -40000 The x term is -150x. Take half its coefficient (-75). Square it (5625) and add it to both sides. Add '5625' to each side of the equation. -150x + 5625 + x2 = -40000 + 5625 Reorder the terms: 5625 + -150x + x2 = -40000 + 5625 Combine like terms: -40000 + 5625 = -34375 5625 + -150x + x2 = -34375 Factor a perfect square on the left side: (x + -75)(x + -75) = -34375 Can't calculate square root of the right side. The solution to this equation could not be determined.
