(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 \((q\times q)\)
O - Outside Times Outside \((q\times[-6])\)
I - Inside Times Inside \(([-5]\times q)\)
L - Last Times Last \(([-5]\times[-6])\)
When you do the \(F.O.I.L.\) method for this expression, you get :
\({q}^{2}-6q-5q+30\)
Now combine like terms
\({q}^{2}-11q+30\)
(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
