Given expression is
[tex]-14p^3+10p^2+4p[/tex]
when we break the individual terms using prime factors
[tex]-14p^3= -2*7*p*p*p\\10p^2=2*5*p*p\\4p=2*2*p[/tex]
so the common factors we can see is 2*p
so The greatest common factor is 2p
So when we Factor out Greatest common factor we get
[tex]2p(-7p^2+5p+2)[/tex]
