You can put this solution on YOUR website! Notes:
* When we multiply a variable to another term that has the same variable, we multiply their coefficients, but add their exponents.
* In this case, would be the same as to say
* And would be the same as to say
* When 1 is the coefficient and/or the exponent, we don't write down. It is known to be understood or implicit.
* So now multiply the coefficients and add the exponents
x(3x) = (1x^1)*(3x^1} = 3x^2
