As a generalization, definitely not! However, when and only when x = 2, x2 = 2x.
"It depends on whether the 2x is a quantity being squared or not.
x² + 2x² = 3x²
That's because you have 1 x² + 2 x² = 3 x²
(one of something plus two of something equals three of something).
However, if you intended for the whole quantity 2x to be squared you would write:
x² + (2x)² = 5 x²
x² + 4x² = 5x²
In Pythagorean terms, if the ratio of the legs were x and 2x, then you'd take the square root of 5x² and get:
√5 * x
So a right triangle with legs in the ratio of 1x to 2x will have a hypotenuse equal to (√5)x"
Dear Norvellwisdom,
I believe that this is your opinion not a fact. I have wrote the correct answer.
Thanks,

Dear Ms. Natalie,
Your have written an answer to a different question: "Is x squared equal to 2x squared. That is not the question as it was stated. According to standard algebraic notation, "2x" equals 2 X x, not either "2x2" or (2x)2.
Thanks, Norvell Wisdom

Does x times x equal 2x?
No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)
What does Sin squared x Cos squared x equal?
sin2 x = (1/2)(1 - cos 2x) cos2 x = (1/2)(1 + cos 2x) Multiplying both you get (1/4) (1 - cos2 2x) Which is equal to (1/4) (1 - (1/2) (1 + cos 4x) = (1/8) (2 - 1 - cos 4x) = (1/8) (1 - cos 4x) Or If it is the trigonomic function, sin squared x and cosine squared x is equal to one
How do you divide 2x squared divided by x?
2x2 ÷ x = 2x
What is 2x squared plus x squared?
The expression 2x squared plus x squared can be simplified by combining like terms. When we add 2x squared and x squared, we get 3x squared. Therefore, the simplified expression is 3x squared.
What is 2x squared plus 5x in factored form?
2x2 + 5x = x*(2x + 5)
Does 2x equal x squared?
only when x is equal to 2
What is X squared plus x squared equal to?
x2 + x2 = 2x2 2x^2
What does x squared minus 2x equal?
x2 - 2x = x(x-2) and that cannot be simplified further.
What does cos squared x - Sin squared x equal?
2 x cosine squared x -1 which also equals cos (2x)
What does x squared minus 2x plus 1 equal?
This expression factors as x -1 quantity squared.
Does x times x equal 2x?
No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)
What does Sin squared x Cos squared x equal?
sin2 x = (1/2)(1 - cos 2x) cos2 x = (1/2)(1 + cos 2x) Multiplying both you get (1/4) (1 - cos2 2x) Which is equal to (1/4) (1 - (1/2) (1 + cos 4x) = (1/8) (2 - 1 - cos 4x) = (1/8) (1 - cos 4x) Or If it is the trigonomic function, sin squared x and cosine squared x is equal to one
Is 2x the same as x squared?
No. x squared is x times x, whereas 2x is x + x.
What is the product of (2x-7y)(x y)?
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
What does x squared - 2x factor out to?
x2 - 2x = x(x-2)
What is x-squared minus 2 x plus 15?
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
How do you divide 2x squared divided by x?
2x2 ÷ x = 2x
