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
The point that passes through the line Y-5=-3(x-4) is (-4,7). You are very welcome.
