Simplifying l2 + 2l + 188 = 0 Reorder the terms: 188 + 2l + l2 = 0 Solving 188 + 2l + l2 = 0 Solving for variable 'l'. Begin completing the square. Move the constant term to the right: Add '-188' to each side of the equation. 188 + 2l + -188 + l2 = 0 + -188 Reorder the terms: 188 + -188 + 2l + l2 = 0 + -188 Combine like terms: 188 + -188 = 0 0 + 2l + l2 = 0 + -188 2l + l2 = 0 + -188 Combine like terms: 0 + -188 = -188 2l + l2 = -188 The l term is 2l. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2l + 1 + l2 = -188 + 1 Reorder the terms: 1 + 2l + l2 = -188 + 1 Combine like terms: -188 + 1 = -187 1 + 2l + l2 = -187 Factor a perfect square on the left side: (l + 1)(l + 1) = -187 Can't calculate square root of the right side. The solution to this equation could not be determined.
