No, x + x equals 2x.
x times x equals x2. (x times x equals x squared.)
It is equal to 2x because if you were to replace the "x" with a number say, 2 for example so 2 + 2 would be 4 and 2 times 2 would also be 4 which is what "2x" stands for (2 times x). So then if you had x + x you would get 2x.
2x * 2x * x = 4x^3
2X+6
2x - (8 x 6) = 20 2x = 20 + 48 2x = 68 x = 68/2 x = 34
x+x=2x
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
x times 2x is 2x squared or 2x2
2x minus 3x is equal to -x.
Sin(x) cos(x) = 1/2 of sin(2x)
2x
only when x is equal to 2
It doesn't; it equals 2x. Only if x = 0 does 2x = x.
