I think u should check the first one again u made a mistake but the second one is correct if u need any more help ask me
77 is a multiple of 11, as i'm sure you know--the double numbers like 22 and 55, one of the factors are always 11.
77 is factored down into 11 and 7--which, when you add those, luckily equal 18.
(x + 11)(x + 7) is your factorization.
