Can some one give me the answers 15 points

I know all the anwers but it won't help you to give you al the answers, so I wil solve all of each type
8 and 9 are similar, so I will solve 9
10 is one
11 is last

I will solve 9,10,11

9.
convert into ax^2+bx+c=0 form
add 4x^2 to both sides
4x^2+5x+9=0
for
ax^2+bx+c=0
x=
x=
x=
x=
no real soltuions, D

(number 8, would be x=, simplify it yourself)

10. difference of 2 perfect squares, recognize it and do no work
(a-b)(a+b)=a²-b²
(3x-4)(3x+4)=(3x)²-(4)²=9x²-16
B

11.
to move an equation c units to the right, minus c from every x
