The key idea is FACTORING. You need to find common factor of each expression and see if there is anything you can cancel out afterwards.
[2(c+3)/(4-c)] * [4(c-4)/5(c+3)]
(c+3) can be cancelled out.
Rewrite (4-c) to -(c-4), then cancel out (c-4).
Therefore, the final simplified answer is 2*4/-5 = 8/-5
6
factor out the 2, the negitive, the 4 and the 5...2(c+3)/-(c-4)*
4(c-4)/5(c+3) then cross cancel leaving 8/-5
