Simplifying y2 + -7y + 29.3 = 0 Reorder the terms: 29.3 + -7y + y2 = 0 Solving 29.3 + -7y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '-29.3' to each side of the equation. 29.3 + -7y + -29.3 + y2 = 0 + -29.3 Reorder the terms: 29.3 + -29.3 + -7y + y2 = 0 + -29.3 Combine like terms: 29.3 + -29.3 = 0.0 0.0 + -7y + y2 = 0 + -29.3 -7y + y2 = 0 + -29.3 Combine like terms: 0 + -29.3 = -29.3 -7y + y2 = -29.3 The y term is -7y. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7y + 12.25 + y2 = -29.3 + 12.25 Reorder the terms: 12.25 + -7y + y2 = -29.3 + 12.25 Combine like terms: -29.3 + 12.25 = -17.05 12.25 + -7y + y2 = -17.05 Factor a perfect square on the left side: (y + -3.5)(y + -3.5) = -17.05 Can't calculate square root of the right side. The solution to this equation could not be determined.
