Use the zero product property.
When you have an equation,
A%2AB=0
Then A=0 and B=0 are both solutions.
In your case,
%28x%2B3%29%28x%2B10%29=0
So then
x%2B3=0
x=-3
and
x%2B10=0
x=-10
.
.
.
The two solutions to your quadratic equation are x=-3 and x=-10.

(x + 3)(x + 10) = 0
----
Since the product is zero, one of those factors must be zero.
----
Either x+3 = 0 or x+10 = 0
---
Then, solving for "x", you would get:
x = -3 or x = -10
========================
Those two values are the solutions for the equation.
