^ 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.
