in this question firstly take -2 as a common and then your equation is n^2+60n-336=0
add both side -10n then your equation become
n^2+60n-336-10n=0-10n
n^2+50n-336=-10n
n^2+56n-6n-336=-10n
take n common
n(n+56)-6(n+56)=-10n
add both side -10n then your equation become
n^2+60n-336-10n=0-10n
n^2+50n-336=-10n
n^2+56n-6n-336=-10n
take n common
n(n+56)-6(n+56)=-10n
kithmini:
are u sure
