I don't know how to put this in standard form:

f(x)=x^2-2x-15

I tried (x^2-2x+-x^2)-25-x^2, but x^2 doesn't factor into anything so I can't fully put it into standard form. can you show me how, plus how to find the x intercepts and y intercepts?

  • Algebra -

    f(x)=(x-1)^2 -16
    and of course, that is a difference of two squares...
