In general, you’ve missed out the “^” sign which denotes “raised to the power”.

So all examples start with x^2 ie x squared.

Which of 10 and 25 is a square?

Which sign (+ or -) denotes “difference”?

x^2-25, because it always has to be a negative so that when you foil (first outter inner last) you can get the middle term to cancel. in this case you would get (x-5)(x+5) so you will get x^2+5x-5x-25 the middle term cancels leaving you with x^2-25.

x² – 25

x^2-25

you can factorise it to (x+5)(x-5)
