The way you make a little 2 is by:
Holding the alt gear on the left hand side of the keyboard and press del at the same time...
holding it and pressing the numbers 2, 5, and 3 you should get "²"
If you want to get a little 2 on a Microsoft website...
Hold the alt gear and press the numbers 0, 1, 7, 8 and there you have it!!! "²"
2x -2 squared = 0
2^2 + 3^2 = 4 + 9 = 13
x^2+2x^2=3x^2
If I have this correct you are asking x^2 + 10^2 = 12^2 Then x=6.633249507108
A^2-2ab+B^2 is actually (A+B)^2 AB squared is A^2B^2 or (AB)^2
a^2b^2c^2 ^2 is squared
The symbol for squared is ², for example, 2 squared would be 2².
It is 8
-3 squared by 2
-2 squared is +4.
The result of a number multiplied by itself
You could just pull out the half: it will be (1/2) cos squared x.
When you subtract 7x^2 from 5x^2, you get -2x^2.
2x -2 squared = 0
8 = 4 + 4 = 2² + 2²
2 squared = 2^(2) = 4
2 squared 3 squared 5 or 180
