(3x)(x2) = 3x3.
Think of this as (3x1)(1x2). First multiply the numbers: (3)(1) = 3. next multiply the variables: (x1)(x2) = x1+2 = x3 (when you multiply powers with the same base, add the exponents)

The expression 3x times x squared can be simplified by multiplying the coefficients and adding the exponents. This results in 3x^1 * x^2, which simplifies to 3x^(1+2) = 3x^3. Therefore, the expression 3x times x squared simplifies to 3x cubed.
Well, darling, 3x times x squared is simply 3x^3. It's like basic math 101, no need to make it complicated. Just multiply the coefficients and add the exponents, easy peasy lemon squeezy!
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
(3x2 - 6x)/3x = 3x(x-2)/3x = x-2, for x<>0
x(3x - 2)
It is: 3x*(x+7)
x^2+2x^2=3x^2
