Step-by-step explanation:
Given:
We need to reduce
by 
Solution:
To reduce the equation means we need to subtract the one equation from other.
First we will arrange the equation n proper format we get;
⇒ equation 1
Also Arranging other equation we get;
⇒ equation 2
Now we will subtract equation 2 from equation 1 we get;

Now Applying distributive property for the sign we get;

Now Arranging the like terms we get;

Hence the reduce form of the given equation is

Answer : B
x^2-9x+14
Lets factor 
We find out two factors whose product is +14 and sum is -9
Two factors are -2 and -7, we split the middle term -9x using -2 and -7

Group first two terms and last two terms
Then factor out GCF from each term



so x-2 is one of the factor
