Answer 7

Answer 8

yes

Answer 9

would it be 3?

Answer 10

cannot....

Answer 11

@frankcookie96 your original idea was correct:
\[\frac{x^2+5x+3}{x}=\frac{x^2}{x}+\frac{5x}{x}+\frac{3}{x}\]

Answer 12

so as the result it would be?

Answer 13

because 3 cannot divide by x or any unknown....

Answer 14

Well you simplify your first two terms and get what?

Answer 15

the 1st one is \[4x ^{2}\] over x which is 4x

Answer 16

@raden_zaikaria the problem is simplifying an expression without knowing x. You can in fact, divide by x.

Answer 17

For the 2nd 5x/x I get 5

Answer 18

So it's 4x + 5 + ?

Answer 19

I copied the equation wrong, apologies. Yes your first term becomes 4x and your second term is 5. Put all three terms together and you get:
\[4x+5+\frac{3}{x}\]

Answer 20

3/x does not simplify any further.

Answer 21
