Simplifying y2 + -3y + 40 = 0 Reorder the terms: 40 + -3y + y2 = 0 Solving 40 + -3y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '-40' to each side of the equation. 40 + -3y + -40 + y2 = 0 + -40 Reorder the terms: 40 + -40 + -3y + y2 = 0 + -40 Combine like terms: 40 + -40 = 0 0 + -3y + y2 = 0 + -40 -3y + y2 = 0 + -40 Combine like terms: 0 + -40 = -40 -3y + y2 = -40 The y term is -3y. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3y + 2.25 + y2 = -40 + 2.25 Reorder the terms: 2.25 + -3y + y2 = -40 + 2.25 Combine like terms: -40 + 2.25 = -37.75 2.25 + -3y + y2 = -37.75 Factor a perfect square on the left side: (y + -1.5)(y + -1.5) = -37.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
