The correct answer is just x.
2x(-x) , all you do is combine like terms . so 2-1 =1 and x=1 so the answer is x.
====================================
Hi, Katerina. Welcome to WA. It's great fun and you'll love it.
But if you're planning to spend much time in Math, then you'll have to
take some of that time out of Anime and Rock and brush up on the Math.
If the question had said "What is 2x plus -x ?", or even "What is 2x and -x ?",
then "just x" would be a correct answer.
But when it says "times", you don't combine like terms. You multiply.
And the product is
(2x) times (-x) = -2x2 .
2x * 2x * x = 4x^3
2x
2x2
No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)
(2x x 3x) x 2 = 12x (2x times 3x times 2)
2x to the fourth
300/2x = 150/x
-2
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
2x+x is 3x
No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)
Yes, 2x is 2 times x.
X * - 2= - 2X========that simple
(2x x 3x) x 2 = 12x (2x times 3x times 2)
It is: -2x squared
(2x)2(x) = 4x3
we write 2 times x as 2x so if x=2, 2x=2(2)=4
x times x = x2 (it's like 6 times 6. it would be 62. not 6 times 2. 2x means x times 2)
2x to the fourth
2x times 4x is 8x squared- then that times x is 8x to the power of three.Mathmatically represented as 8x^3
