No.
x squared is x times x, whereas 2x is x + x.
Only when x=2
x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
2x to the fourth
3x squared - x squared = 2x squared
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
2x2 + 2x = 2x(x+1)
2 squared X 3 squared = 5 squared
x(x + 2)
