Simplifying c2 + -3c + 9 = 0 Reorder the terms: 9 + -3c + c2 = 0 Solving 9 + -3c + c2 = 0 Solving for variable 'c'. Begin completing the square. Move the constant term to the right: Add '-9' to each side of the equation. 9 + -3c + -9 + c2 = 0 + -9 Reorder the terms: 9 + -9 + -3c + c2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -3c + c2 = 0 + -9 -3c + c2 = 0 + -9 Combine like terms: 0 + -9 = -9 -3c + c2 = -9 The c term is -3c. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3c + 2.25 + c2 = -9 + 2.25 Reorder the terms: 2.25 + -3c + c2 = -9 + 2.25 Combine like terms: -9 + 2.25 = -6.75 2.25 + -3c + c2 = -6.75 Factor a perfect square on the left side: (c + -1.5)(c + -1.5) = -6.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
