Simplifying 3y2 + -6y + 16 = 0 Reorder the terms: 16 + -6y + 3y2 = 0 Solving 16 + -6y + 3y2 = 0 Solving for variable 'y'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 5.333333333 + -2y + y2 = 0 Move the constant term to the right: Add '-5.333333333' to each side of the equation. 5.333333333 + -2y + -5.333333333 + y2 = 0 + -5.333333333 Reorder the terms: 5.333333333 + -5.333333333 + -2y + y2 = 0 + -5.333333333 Combine like terms: 5.333333333 + -5.333333333 = 0.000000000 0.000000000 + -2y + y2 = 0 + -5.333333333 -2y + y2 = 0 + -5.333333333 Combine like terms: 0 + -5.333333333 = -5.333333333 -2y + y2 = -5.333333333 The y term is -2y. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2y + 1 + y2 = -5.333333333 + 1 Reorder the terms: 1 + -2y + y2 = -5.333333333 + 1 Combine like terms: -5.333333333 + 1 = -4.333333333 1 + -2y + y2 = -4.333333333 Factor a perfect square on the left side: (y + -1)(y + -1) = -4.333333333 Can't calculate square root of the right side. The solution to this equation could not be determined.
