Question 810637
Look for the greatest common factor of the terms, of ALL the terms.


{{{2*2*2*p^6-2*2*5*p^4+2*2*3*3*p^3-2*2*2*2*p^2}}}


Looking carefully you should identify {{{2*2*p^2}}} as the greatest common factor.  Continue with that.



The question about factoring by grouping of terms - might not be practical or possible.  Let's see what happens if we factor by reverse distrubution of the greatest common factor:


{{{(2*2*p^2)(2p^4-5p^2+3*3p-2*2)}}}
{{{(4p^2)(2p^4-5p^2+9p-4)}}}
I see nothing more.
