Simplifying y2 + -14y + 49 = -225 Reorder the terms: 49 + -14y + y2 = -225 Solving 49 + -14y + y2 = -225 Solving for variable 'y'. Reorder the terms: 49 + 225 + -14y + y2 = -225 + 225 Combine like terms: 49 + 225 = 274 274 + -14y + y2 = -225 + 225 Combine like terms: -225 + 225 = 0 274 + -14y + y2 = 0 Begin completing the square. Move the constant term to the right: Add '-274' to each side of the equation. 274 + -14y + -274 + y2 = 0 + -274 Reorder the terms: 274 + -274 + -14y + y2 = 0 + -274 Combine like terms: 274 + -274 = 0 0 + -14y + y2 = 0 + -274 -14y + y2 = 0 + -274 Combine like terms: 0 + -274 = -274 -14y + y2 = -274 The y term is -14y. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14y + 49 + y2 = -274 + 49 Reorder the terms: 49 + -14y + y2 = -274 + 49 Combine like terms: -274 + 49 = -225 49 + -14y + y2 = -225 Factor a perfect square on the left side: (y + -7)(y + -7) = -225 Can't calculate square root of the right side. The solution to this equation could not be determined.
