JudyAs 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
What is x squared times 2x squared?
To find the product of x squared and 2x squared, you multiply the coefficients (2 and 1) to get 2, and then add the exponents of x (2 and 2) to get x to the power of 4. Therefore, x squared times 2x squared is equal to 2x^4.
What is 2x squared plus x squared?
Oh, dude, that's like basic math, right? So, 2x squared plus x squared is just 3x squared. It's like adding apples to apples, but with math. Easy peasy lemon squeezy!
What is 2x squared plus 5x in factored form?
2x2 + 5x = x*(2x + 5)
