I am not sure what you want but Rosala has answered you. Thanks Rosala
ur welcome melody !
9 is a common factor of 45 and 21^2
oh so i think u needed the common factor of 45 and 21^2 ! u should have written that !
The question actually says factor - which is strange since there are no pronumerals (letters)
Perhaps this is what the asker wanted. But it is hard to tell.
45+2l^2 = 9*5+3*7*3*7 = 9*5+9*49 = 9(5+49)
if he wanted this then he should be much more clear !
