Simplifying y2 + -8y + 28 = 0 Reorder the terms: 28 + -8y + y2 = 0 Solving 28 + -8y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '-28' to each side of the equation. 28 + -8y + -28 + y2 = 0 + -28 Reorder the terms: 28 + -28 + -8y + y2 = 0 + -28 Combine like terms: 28 + -28 = 0 0 + -8y + y2 = 0 + -28 -8y + y2 = 0 + -28 Combine like terms: 0 + -28 = -28 -8y + y2 = -28 The y term is -8y. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8y + 16 + y2 = -28 + 16 Reorder the terms: 16 + -8y + y2 = -28 + 16 Combine like terms: -28 + 16 = -12 16 + -8y + y2 = -12 Factor a perfect square on the left side: (y + -4)(y + -4) = -12 Can't calculate square root of the right side. The solution to this equation could not be determined.
