First question: 1/x^2-36}-{x+3/x^2-7x+6
-
Note that the 1st denominator is the "difference of squares"
2nd denominator can be factored also;
-
The common denominator is(x-6)(x+6)(x-1)
we have:
= = ; removing brackets changes signs
Combining like terms;
= =
Second question: 16 minus 1 over y^2 over 4 plus 1 over y
----------
:
We want each written as a single fraction:
----------
:
Invert the dividing fraction and multiply
*
:
16y^2 - 1 is the difference of squares, factor that to
*
;
Some simple canceling and you have:
:
:
"1/x^2-36 is a fraction as is x+3/x^2-7x+6 I am to subtract and then simplify if possible.

This is exactly the same as the 1st problem
