Simplify completely... x^2+x-12/x^2-x-20 divided by 3x^2-24x+45/12x^2-48x-60?Please explain how to do? Thanks.
(1) Dividing by fractions or rational expressions is the same as multiplying by the reciprocal, so an equivalent expression to simplify is:
(2) Factor the trinomials:
(3) Cancel common factors of the numerator and denominator:
`(4(x+1))/(x-5)` which is fully simplified.
