Question

Hey can you please help me posted picture of question :)

Answer 1

The solutioms for the equation are a and b or -3 & -6

Answer 2

Answer:
The solutions are -3 and -6

Step-by-step explanation:
First we would need to put the equation in standard form which is:
ax² + bx + c = 0
This can be done as follows:
x² + 18 = -9x
x² + 9x + 18 = 0
By comparison, we would find that:
a = 1
b = 9
c = 18

Now, to get the roots, we would use the quadratic formula shown in the attached image.

By substitution, we would find that:
either x =
`(-9+ √((9)^2-4(1)(18)) )/(2(1)) = -3`

or x =
`(-9- √((9)^2-4(1)(18)) )/(2(1)) = -6`

Hope this helps :)
