only 3 more ! sorry for askin for all the help, im in the middle or moving, and keeping track of kids, and doing work, thanks so much for the help.

Divide as indicated.

Question

only 3 more ! sorry for askin for all the help, im in the middle or moving, and keeping track of kids, and doing work, thanks so much for the help.

Divide as indicated. 
12x^2/x-3  /  15x^2+25/x^2-9

anonymous · Answer

$$12x ^{2}+20/x-3  \div  15x ^{2}+25/x ^{2}-9$$

anonymous · Answer

is that [(12x^2+20)/(x-3)]/[(15x^2+25)/(x^2-9)]

anonymous · Answer

yes

anonymous · Answer

the answer is (4/5)(x+3) would you like to know how to do it?

anonymous · Answer

please

anonymous · Answer

ok, let me work it out real quick then

anonymous · Answer

sorry computer died. first factor out a 4 from 12x^2+20 giving you 4(3x^2+5). Now factor out a 5 from 15x^2 + 20 giving you 5(3x^2+5). Third factor x^2-9 into (x-3)(x+3). now the (x-3)'s will cancel out along with the (3x^2+5) giving you 4/5/(x+3) bringing to the top gives you (4/5)*(x+3)
