Simplifying x2 + -9x = -40 Reorder the terms: -9x + x2 = -40 Solving -9x + x2 = -40 Solving for variable 'x'. Reorder the terms: 40 + -9x + x2 = -40 + 40 Combine like terms: -40 + 40 = 0 40 + -9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-40' to each side of the equation. 40 + -9x + -40 + x2 = 0 + -40 Reorder the terms: 40 + -40 + -9x + x2 = 0 + -40 Combine like terms: 40 + -40 = 0 0 + -9x + x2 = 0 + -40 -9x + x2 = 0 + -40 Combine like terms: 0 + -40 = -40 -9x + x2 = -40 The x term is -9x. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9x + 20.25 + x2 = -40 + 20.25 Reorder the terms: 20.25 + -9x + x2 = -40 + 20.25 Combine like terms: -40 + 20.25 = -19.75 20.25 + -9x + x2 = -19.75 Factor a perfect square on the left side: (x + -4.5)(x + -4.5) = -19.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
