Simplifying c2 + -7c + 20 = 0 Reorder the terms: 20 + -7c + c2 = 0 Solving 20 + -7c + c2 = 0 Solving for variable 'c'. Begin completing the square. Move the constant term to the right: Add '-20' to each side of the equation. 20 + -7c + -20 + c2 = 0 + -20 Reorder the terms: 20 + -20 + -7c + c2 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + -7c + c2 = 0 + -20 -7c + c2 = 0 + -20 Combine like terms: 0 + -20 = -20 -7c + c2 = -20 The c term is -7c. 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. -7c + 12.25 + c2 = -20 + 12.25 Reorder the terms: 12.25 + -7c + c2 = -20 + 12.25 Combine like terms: -20 + 12.25 = -7.75 12.25 + -7c + c2 = -7.75 Factor a perfect square on the left side: (c + -3.5)(c + -3.5) = -7.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
