Answer 2

\(\log a - \log b = \log \dfrac{a}{b} \)
Can you factor those polynomials?

Answer 3

Use the rule of logs above to rewrite this as the log of a fraction.
Then factor the numerator and denominator and see if any terms cancel out.

Answer 4

how do i factor the top one? x^3-125?

Answer 5

\[\huge\rm (x^3 - b^3) = (x-y)(x^2 +xy+y^2)\]
