x squared -2
How to solve is listed below
x*x +2x - 2x -2
Sorry, I don't know how to do the squared button.

x(x +2) - (x + 1)
= x²+2x-x-1
= x²+x-1

x(x +2) - 2(x + 1)
If a ( - ) sign precedes a parenthesis all signs inside the parenthesis change.
x² + 2x - 2x - 2
The distributive property
X² - 2
+ 2 and - 2 cancell
The answer is x² - 2

x^2 + 2x - 2x + 2
= x^2 + 2

x(x+2)-2(x+1)
Multiply all of the components in the first parenthesis by x:
x^2+2x-2(x+1)
Multiply all of the components in the last parenthesis by negative 2:
x^2+2x-2x-2
2x minus 2x equals 0:
x^2-2
Final Answer:
x squared minus 2.

x*x + x*2-2*x-2*1
= x^2+2x-2x-2
= x^2-2

x(x+2) - 2(x+1) = (x^2 +2x) - (2x + 2)
= x^2 +2x -2x -2
= x^2 -2

For mariposa.
To get x², type the x and then hold down the ALT key and type 235. Check out

For all of the other extended ASCII characters such as Ï and so forth. They're all formed the same way: Hold down ALT and type the three digit decimal character code.
