Solution for ln((x^2)-1)-ln(x-1)=ln(6) equation:


Simplifying
ln((x2) + -1) + -1ln(x + -1) = ln(6)
ln(x2 + -1) + -1ln(x + -1) = ln(6)

Reorder the terms:
ln(-1 + x2) + -1ln(x + -1) = ln(6)
(-1 * ln + x2 * ln) + -1ln(x + -1) = ln(6)
(-1ln + lnx2) + -1ln(x + -1) = ln(6)

Reorder the terms:
-1ln + lnx2 + -1ln(-1 + x) = ln(6)
-1ln + lnx2 + (-1 * -1ln + x * -1ln) = ln(6)
-1ln + lnx2 + (1ln + -1lnx) = ln(6)

Reorder the terms:
-1ln + 1ln + -1lnx + lnx2 = ln(6)

Combine like terms: -1ln + 1ln = 0
0 + -1lnx + lnx2 = ln(6)
