Yes I Am Can You Help Me Set It Up ?

Answer 9

quadratic equation: \(\large ax^2+bx+c=0 \)
your equation: \(\large x^2+9x+9=0 \)

first you need to identify these values
a=
b=
c=

can you do that?

Answer 10

a= 1
b=9
c=9

Answer 11

ok.. now all you have to do is compute:

\[\large x=\frac{-(9)\pm\sqrt{(9)^2-4(1)(9)}}{2(1)} \]
