$$(x - 11)(x - 7)$$
To factor this polynomial, we want to see the combinations of factors for $77$ that will add up to $-18$, the coefficient for the middle term: The factors for $77$ are: $77$ and $1$ or $-77$ and $-1$ $11$ and $7$ or $-11$ and $-7$ The factors $-11$ and $-7$ will work in this case because when added up, they equal $-18$: $$(x - 11)(x - 7)$$
