Question

can someone explain to me how to solve
5x^2-21x-20/5x^2-16x-16

Answer 1

factor:
((x-5)(5x+4))/((x-4)(5x+4))
cancel out 4x+4
(x-5)/(x-4)

Answer 2

*5x+4

Answer 3

I think you mean how to symplify or do the division.

Answer 4

both?

Answer 5

Did you understand how to solve the problem? Can you do a similiar problem by yourself?

Answer 6

i can do problems such as : 4x+3/5 but when it becomesmore than that it becomes confusing

Answer 7

that was just an example

Answer 8

So if you have something like \[\frac{4x+3}{x+5}\] you have problems

Answer 9

i've never done a problem like that in my lessons, i've had things like
x^2-15x+56/ x-7 or with more terms

Answer 10

practice factoring, if you are good at factoring those problems become easy
