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
The given expression is
And in the second factor, x is common. So on taking x out, we will get
We can expand it by distributing , that is
Combining like terms,
And that's the expanded form ., and the given expression can also be written in that way .
