( 2q - 4 ) ( 9q - 8 )
Simplify this expression !
Please answer this !!

Question 2

You can’t simplify it? You solve it by combining like terms

18q^2-52q+32

Question 3

$\bf{Hey\ there!}\\ \bold{(2p-4)(9q-8)}\\ \bold{Distribute\downarrow}\\\bold{(2q-5)(9q-8)} \\ \bold{2q(9q)=18q^2}\\\bold{2q(-8)=-16q}\\\bold{-4(9q)=-36q}\\\bold{-4(-8)=32}$

$\bold{Combine\ like\ terms\downarrow}\\\bold{\bullet\ -16q+-36}$

$\bold{-16+-36=-52}$

$\bold{18q^2\ stays\ the\ same\ because\ it\ doesn't\ have\ a\ like\ terms}$
$\bold{\&}$
$\bold{32\ stays\ the\ same\ as\ well\ because\ it\ also\ doesn't\ have\ a\ like\ term\ as\ well}$
