That's not readable: in other words, makes no sense!
Post the problem in full; ask someone to show you how to type math stuff properly.

The 3rd one is ok; do the multiplication: (x - 3) times (2x - 1);
if you can't, you need classroom help.

Are you requesting lessons on some particular aspect of these topics?

1. y2-25

Does the above possibly mean "y^2 - 25" (also written "y² - 25")? Were there any instructions?

2. 64x6y12

Does the above possibly mean "64 x^6 y^12" (also written "64x⁶y<sup.12</sup>")? Were there any instructions?

3. (x-3)(2x-1)=0

Were you possibly supposed to solve this equation? Has your class covered the "zero product" property?

Please reply with clarification and specifics, showing everything you have tried so far. Thank you.
