Answer:...
-4+8x+2xy
Step-by-step explanation:

Use the rational zero theorem
In rational zero theorem, the rational zeros of the form +-p/q
where p is the factors of constant
and q is the factors of leading coefficient

In our f(x), constant is 2 and leading coefficient is 14
Factors of 2 are 1, 2
Factors of 14 are 1,2, 7, 14
Rational zeros of the form +-p/q are

Now we separate the factors


We ignore the zeros that are repeating

Option A is correct
9/15 becomes 90/15 but now u have a point on ur answer so it would be .6 as 15 times 6 equals 90
