if you mean
(3/(2x-5))(21/(8x2-14x-15))
you would get
(63/( (2x-5)(4x+3)(2x-5) )
simplified more would be
63/ ( (2x-5)2(4x+3) )
By factoring I get x-3 divided by x+3
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y) 2. 1/x - 2/x2 + x = (x - 2 + x3)/x2 which can be simplified (?) to (x-1)(x2+x+2)/x2.
97/100 − 40/100 = 57/100
3/1000 cannot be simplified further.
This is in simplest form.
2
It is (4x + 2)
4/9 - 5/12 = 1/36 (In simplified form)
By factoring I get x-3 divided by x+3

20 over 13
1/2x^3
It is already in simplified form.
b over the square root of 5 The square root of 5b squared is 5b, and the simplified form of the square root of 125 is 5 root 5. The 5s then cancel out leaving b over the square root of 5.
16 over 52 simplified in fraction form is 4/13
10 over 52 simplified in fraction form is 5/26
