(4+x) (2x-3)
x2 - 2x = x(x - 2)
x(4x-2)
(2x - 1)(x + 3)
64-x2 = (8-x)(8+x) when factored

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) )
It is: x-1+4+7x-3 = 8x simplified
x^2 - y^2 - 4 is in its simplest form.
(4x-8)(2x+2)
(4+x) (2x-3)
x(4x-2)
x2 - 2x = x(x - 2)
(2x - 1)(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.
