Simplifying 13 + -6y + y2 = 0 Solving 13 + -6y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + -6y + -13 + y2 = 0 + -13 Reorder the terms: 13 + -13 + -6y + y2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + -6y + y2 = 0 + -13 -6y + y2 = 0 + -13 Combine like terms: 0 + -13 = -13 -6y + y2 = -13 The y term is -6y. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6y + 9 + y2 = -13 + 9 Reorder the terms: 9 + -6y + y2 = -13 + 9 Combine like terms: -13 + 9 = -4 9 + -6y + y2 = -4 Factor a perfect square on the left side: (y + -3)(y + -3) = -4 Can't calculate square root of the right side. The solution to this equation could not be determined.
