3x2 - 2x - 5 = (3x - 5)(x + 1) = 0 gives a solution of x = 5/3 or -1. Was that what you wanted?
3x squared - x squared = 2x squared

Not sure what you are asking, clearly 6x is 3x plus 3x.But the question asks "what is 3x equals 3x?""3x equals 3x" is a tautology.(A logical tautology is a statement that is true regardless of the truth values of its parts)If you are asking what the value of x is, this equation is true for any value of x.All numbers are a solution of "3x equals 3x."But the question is not very clear so please add some discussion to help?
-3x = 9x = 9/(-3)x = -3

3x - 5 = 48 So 3x = 53 and x = 53/3 = 17.66...
True because in both equations x = 0 or x = -4
3x(2x + 1)
It is a quadratic equation in X.

3x squared - (3x) squared = 0

3x-5=3x+5 There is no solution.
