I have a few math questions I made them just like my actual problems so that I can go through the steps you have went through to answer my own problems...Again THESE ARE NOT THE REAL PROBLEMS JUST EXAMPLES LIKE MINE WITH DIFFERENT NUMBERS. I don't know how to complete these problems so I made up some to learn how to do my actual problems.
I am unsure how to make a radical sign with the keyboard so I am using a question mark in its place.
(2?5?28)(?28+4?5)
(?3+2?5)^2
(3?76?2)(7?7+?2)
(4x?y+2)(4x?y?2)
(6?25?5)(3?2+2?5)
Thank you for helping.

For √, type in
& r a d i c ;
but without the intervening spaces.
I will solve the first one:
Use the FOIL rule
(2√5√28)(√28+4√5)
=(2√52√7)(2√7+4√5)
=4(√5√7)(√7+2√5)
=4(107√5√7)
=124√5√7
