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+2) - 2(x+1) = x²+2x-2x-2

= x²-2

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

x squared - 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 π and so forth. They're all formed the same way: Hold down ALT and type the three digit decimal character code.
