Reduction of a relationship to linear form

Sorry this isnt urgent home work but I couldnt figure out what section to put this under.

I have been given y = 1/(x-a)(x-b)

and have to explain how i would verify the relationship graphically and then how to determine a and b from the graph. i know i just have to do a sketch.

im assuming i have to take logs to get it into the format of y = mx+c

but i keep going round in circles.

Then im guessing to work out a and b its just going to be the gradient and intercept. Ive done a few of these but none where there are two x's and its thrown me(Worried)

Any pointers in the right direction would be appriciated

thanks in advance and hope this make sense(Happy)(Happy)
