The first step for solving this expression is to write the division as a fraction.
x + [tex] \frac{7x}{9} [/tex] × x
Calculate the product.
[tex] \frac{7x X x}{9}[/tex]
Remember that if a term doesn't have an exponent,, it is considered that the exponent for that term is 1. This changes the expression to the following:
[tex] \frac{7 x^{1}X x^{1} }{9} [/tex]
Now multiply the terms with the same base by adding their exponents.
[tex] \frac{7 x^{1+1}}{9}[/tex]
Finally,, add the numbers together to get your final answer.
x + [tex] \frac{7 x^{2}}{9}[/tex]
