(4z-u)(6z+4u)?
First: mult the first two terms: 4z*6z = 24z^2
Outer: mult the first & last terms: 4z*4u = 16zu
Inner: mult the inner terms: -u*6z = -6zu
Last: mult the last terms: -u*4u = -4u^2
:
Put them together
24z^2 + 16zu - 6zu - 4u^2
:
the middles are like terms combine them
24z^2 + 10zu - 4u^2
