^ means square
Step-by-step explanation:
(3*2y -5z) (2*-5y +2z)
= (6y -5z) (-10y +2z)
Opening the brackets →
= 6y (-10y +2z) -5z (-10y +2z)
= -60y^2 +12yz +50yz -10z^2
= -60y^2 +62yz -10z^2
This is the final answer ↑ since all the variables are now different and cannot be further added / simplified.
