(q-5)(q-6) using the FOIL method.
First: q*q=q2
Outside: q*(-6)=-6q
Inside: (-5)*q=-5q
Last: (-5)*(-6)
q2-6q-5q+30
q2-11q+30
(q−5)(q−6)
F.O.I.L.
F - First Times First (q×q)
O - Outside Times Outside (q×[−6])
I - Inside Times Inside ([−5]×q)
L - Last Times Last ([−5]×[−6])
When you do the F.O.I.L. method for this expression, you get :
q2−6q−5q+30
Now combine like terms
q2−11q+30
(q-5)(q-6) using the FOIL method.
First: q*q=q2
Outside: q*(-6)=-6q
Inside: (-5)*q=-5q
Last: (-5)*(-6)
q2-6q-5q+30
q2-11q+30
