Negative x multiplied by 2 is negative 2x but negative x multiplied by (2) is positive x.
The above answer is not correct, sorry. As the question is stated, indeed -x2 does equal -x2. Now, I would imagine that the person asking the question really wanted to state it using squares: Why is -x^2 not equal to (-x)^2? (NOTE: the caret "^" means "raised to a power") In this case no mater what x is (negative or positive) the second term will always be positive (if x is negative then -x = +x and +x squared will be positive.) The first term however could be negative or positive depending on what x is. If x is positive then the term will be negative because the "square" is only squaring the x not the negative sign. If x is negative then the term will be positive ( -(-x) = +x). Hope this helps!

What the derivetive of x2?
Any monomial in the format: axn has a derivative equal to: nax(n - 1) In this case, "a" is equal to 1 and "n" is equal to 2. So the derivative of x2 is equal to 2x.

x2 + x2 = 2x2 2x^2
Can variables with exponents that are being multiplied be combined?
You can combine like variables but not unlike variables.So, for example, x2 * x2 = x4 but x2 * y2 does not equal xy4!Let's make x equal 2 and y equal 3 just to demonstrate this.So if x2 * x2 = x4 then 22 * 22 = 24 which would mean 4 * 4 = 16 (Yes, that's right)But x2 * y2 can not be combined. 22 * 32 = 4 * 9 = 36 (which is not equal to a combination of x and y to the power 4).
