Question

simplify the given rational expression
66x(2x-5)
----------
18x^3(2x-5)^2

Answer 1

\[\frac{11}{3x^2 (2x-5)}\]

Answer 2

Why do people post answers without explaining the intermediate steps? That's useless.

Answer 3

Not really. If people ask for steps, we give them. It;s not a big issue.

Answer 4

You realize 95% of people will simply copy the answer without learning anything, right?

Answer 5

[ 66x(2x-5) ] / [ 18x³(2x-5)² ]
[ 66x(2x-5) ] / [ 18x³(2x-5)² ]
x in both top and bottom
[ 66(2x-5) ] / [ 18x²(2x-5)² ]
(2x - 5) in both top and bottom
[ 66 ] / [ 18x²(2x-5) ]
6 in both top and bottom (66 is 6*11)
[ 11 ] / [ 3x²(2x-5) ]
There's your final answer.

11/ [ 3x²(2x-5) ]

Answer 6

actualy i have the answer already (teachers weird) trying to figure out how to actually solv the damn thing lol

Answer 7

Should also note that 18x³(2x-5)² cannot be zero, so x can't equal 5/2 and 0. Set both of the parts to 0 and solve for x to find that.

Answer 8

Agreed.
For example, But let's say i post the whole long working and in the end the asker just looks at the answer and runs away.. it wastes our time..

Answer 9

Yeah, that's a good point.

Answer 10

Answer 11

I've been tutoring for more than a year.
And i know it's an old debate. ;)

Answer 12

Whether or not they want an explanation, if they just get an answer then they still won't know how to do it.

Answer 13

The sad part is the people that spend hours scanning their whole homework and posting every single problem here. If they took the time to read their material instead, I bet they would actually be able to solve the questions themselves in the same amount of time :(

Answer 14

Agreed.

Answer 15
