If N is the numerical value of term independent of x in the expansion of 2x2-3x15 ,  then number of prime factors of N is

The term independent of x, r=npp+q=303=1011 th term is term independent of xhence, N=15C10t25⋅310=15⋅14⋅13⋅12⋅115⋅4⋅3⋅2⋅4⋅25⋅310=25⋅311⋅7⋅11⋅13The number of prime factors of N are 5
