Simplifying ln(x2 + x + 1) + x + x4 = 0 Reorder the terms: ln(1 + x + x2) + x + x4 = 0 (1 * ln + x * ln + x2 * ln) + x + x4 = 0 (1ln + lnx + lnx2) + x + x4 = 0 Solving 1ln + lnx + lnx2 + x + x4 = 0 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-1x' to each side of the equation. 1ln + lnx + lnx2 + x + -1x + x4 = 0 + -1x Combine like terms: x + -1x = 0 1ln + lnx + lnx2 + 0 + x4 = 0 + -1x 1ln + lnx + lnx2 + x4 = 0 + -1x Remove the zero: 1ln + lnx + lnx2 + x4 = -1x Add '-1x4' to each side of the equation. 1ln + lnx + lnx2 + x4 + -1x4 = -1x + -1x4 Combine like terms: x4 + -1x4 = 0 1ln + lnx + lnx2 + 0 = -1x + -1x4 1ln + lnx + lnx2 = -1x + -1x4 Reorder the terms: 1ln + lnx + lnx2 + x + x4 = -1x + x + -1x4 + x4 Combine like terms: -1x + x = 0 1ln + lnx + lnx2 + x + x4 = 0 + -1x4 + x4 1ln + lnx + lnx2 + x + x4 = -1x4 + x4 Combine like terms: -1x4 + x4 = 0 1ln + lnx + lnx2 + x + x4 = 0 The solution to this equation could not be determined.
