Answer:

b = -6.307 or -11.693

Explanation:

$b^(2) +9b +13\\$

This can't be factored so you need to use the quadratic formula which is

-b ±
$\frac{\sqrt{b^(2) -4ac}}{2a}$

Plugging the numbers from the equation in, it's

-(9) ±
$\frac{\sqrt{(9)^(2)-4(1)(13) } }{2(1)}$

This simplifies down to b = -6.307 or -11.693.

These are both real solutions.
