Hey can you me posted picture of question : )

The solutions are:
x = -5
x = -6

Explanation:
To get the solution, we can either use a graphical method or an algebraic method.

1- graphical method:
The solution of the equation would be the values of the x-intercept.
Graphing the equation (check attached image), we would find that the solutions are: -6 and -5

2- algebraic method:
The general formula of the quadratic equation is:
ax² + bx + c = 0
The given equation is:
x² + 11x + 30 = 0
By comparison:
a = 1
b = 11
c = 30
To get the roots, we will substitute in the quadratic formula  (attached in the images)
Doing this, we will find that:
either x = = -5

or x =  = -6

Hope this helps :)
