For this case we have the following polynomial:

[tex] 0 = x ^ 2 + 8x + 15
[/tex]

We can rewrite the polynomial by factoring the expression.

We have then:

[tex] (x + 3) (x + 5) = 0
[/tex]

From here, we look for the solutions of the polynomial.

We have then:

Solution 1:

[tex] x + 3 = 0

x = -3
[/tex]

Solution 2:

[tex] x + 5 = 0

x = -5
[/tex]

Answer:

The solutions of the polynomial are given by:

[tex] x = -3

x = -5 [/tex]
