Answer 2

try to use the quadratic formula

Answer 3

or, in this case some simple algebra should do it

Answer 4

I believe it is D

Answer 7

the wording is hurting my eyes but i believe they did something akin to this

8p = -2x2 - 100

2x2 = -8p - 100

then divided a 2 and sqrted

Answer 8

so negative, minus, over 2 is what im looking for

Answer 9

So it would be C, the 8p is negative and then minus 100 over 2?

Answer 10

with any luck yes :)
