Basically, you just need to simplify it first, then combine like terms.
(-4-x)-(3y-9x)
= -4 - x - (3y - 9x)
= -4 - x + -1(3y) + -1 (-9x)
= -4 + -x + -1(3y) + -1(-9x)
= -4 + -x + -3y + 9x
= (-x + -9x) + (-3y) + (-4)
= 8x + (-3y) + (-4)
= 8x - 3y - 4

A.
alright
we can factor out the b² from everybody

b²(5x²+14x-3)
use ac method
for ax²+bx+c
multiply ac, and remember te result
find what 2 numbers multiply to ac and add to get b
split b up into those 2 numbers
factor
it's confusing so see example below
so

b²(5x²+14x-3)
5 times -3=-15
what 2 numbers multiply to get -15 and add to get 14?
15 and -1
b²(5x+15x-1x-3)
group
b²((5x²+15x)+(-1x-3))
b²(5x(x+3)-1(x+3))
factor
b²(5x-1)(x+3)

B.
what 2 numbers multiply to get 81 and add to get -18?
-9 and -9
(x-9)(x-9) or
(x-9)²

C.
diff of 2 perfect squares
remember a²-b²=(a+b)(a-b)
so
x²-11²=(x+11)(x-11)
