The expression 2x squared minus x squared simplifies to x squared. This is because when subtracting like terms, you subtract the coefficients while keeping the variable and its exponent the same. In this case, 2x squared minus x squared leaves you with just x squared.

Well, honey, 2x squared minus x squared is just x squared. It's like taking two scoops of ice cream and then deciding you only want one scoop - you're left with just x squared. Math can be simple when you break it down like that!
x2 - (2x)2 = x2 - 4x2 = -3x2
x2 - 2x2 = -x2
The equation: 2x2 - x
Plug in a number: like 10
2 * 102 - 10 = 2 * 100 - 10 = 200 - 10 = 190
In this case x would equal ten.
x(x - 2)
(x + 2)(x - 4)
It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3
2(x - 7)(x - 1)
- ln ((x^2)-4)
