Hi Makayla;
area=pi(r2)
This is actually an equation, not expression.  An expression does not have the = sign.
area=pi(5p-3m)2
We can expand the parenthetical equation.
Let's FOIL (5p-3m)(5p-3m)
FIRST...(5p)(5p)=25p2
OUTER...(5p)(-3m)=-15pm
INNER...(-3m)(5p)=-15pm
LAST...(-3m)(-3m)=9m
25p2-30pm+9m
area=pi(25p2-30pm+9m)
