Algebraic expressions. if somebody is good at this. i have more than one question about them.

9xa(5x^2 + 3a). This is answer you get after factoring the answer

Notice how the left hand side has a common factor of 9xa on both terms.
Then, you can factorise a 9ax outside.

Now, in order to keep the equality the same, we need to divide the first term by 9ax. 45x³a/9ax can be rewritten as 9ax(5x²).

Let's do the same with the second term.
27xa²/9ax = 9ax(3a)

So, we have 9ax(5x²) + 9ax(3a) = 9ax(5x² + 3a)

So, our answer would be 5x² + 3a
