Simplifying c2 + 8c + 48 = 0 Reorder the terms: 48 + 8c + c2 = 0 Solving 48 + 8c + c2 = 0 Solving for variable 'c'. Begin completing the square. Move the constant term to the right: Add '-48' to each side of the equation. 48 + 8c + -48 + c2 = 0 + -48 Reorder the terms: 48 + -48 + 8c + c2 = 0 + -48 Combine like terms: 48 + -48 = 0 0 + 8c + c2 = 0 + -48 8c + c2 = 0 + -48 Combine like terms: 0 + -48 = -48 8c + c2 = -48 The c term is 8c. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8c + 16 + c2 = -48 + 16 Reorder the terms: 16 + 8c + c2 = -48 + 16 Combine like terms: -48 + 16 = -32 16 + 8c + c2 = -32 Factor a perfect square on the left side: (c + 4)(c + 4) = -32 Can't calculate square root of the right side. The solution to this equation could not be determined.
