9-x^2/9x+27

x-3/9

3-x

x+3/9

3-x/9

It's the last choice: (3 - x) / 9.

Step-by-step explanation:

9-x^2/9x+27

= (3 + x) (3 - x) / 9 (x + 3) The 3 + x is common to top and bottom, so:

the answer is (3 - x) / 9.

3-x/9

Step-by-step explanation:

we have expression

9-x²/9x+27

by making square of the terms and taking common

3²-x²/9 (x+3)

as we know a²-b² = (a+b) (a-b)

so

(3+x) (3-x) / 9 (x+3)

rearrange

(x+3) (3-x) / 9 (x+3)

subtracting (x+3) from denominator and nominator

3-x/9

3-x/9 is the right answer
