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.
x squared + C.
x(x - 2)
x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
x2 - 2x = x(x-2)
2x2 ÷ x = 2x
Add the x's squared together to get 2x^2+x. You cannot add anymore so the answer is 2x^2+x
It is: -2x squared
3x squared - x squared = 2x squared
2x2 + 2x = 2x(x+1)
2 squared X 3 squared = 5 squared
x(x + 2)

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