please post each question separately
thanks

turingtest · Answer

$${x^2-16\over2x^2-9x+4}\div{2x^2+14x+24\over4x+4}$$factor each part as much as possible
you can start by noticing the difference of squares on the top-left term

anonymous · Answer

(x+4)(x-4)/(2x-10(x-4) times 4(x+4)/2(x+6)(x+4)
=x-4/2(x-5) times 2/x+6
=x-4/(x+6)(x-5)...

turingtest · Answer

start with a smaller part of the problem:$$x^2-16$$^^^can you factor this???

anonymous · Answer

4

turingtest · Answer

no, this is a difference of squares, which always can be factored as$$a^2-b^2=(a+b)(a-b)$$
