Answer:
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
Answer:
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.
