Thank you for the opportunity to help you with your question!

Solution:

x^2+13x+36

=> x2 + 4x + 9x + 36

=>(x+9)*(x+4)



Please let me know if you need any clarification. I'm always happy to answer your questions.

It is simple now:

x^2+13x+36

=> x2 + 4x + 9x + 36

=>(x+9)*(x+4)

Setting equal to zero,

=>(x+9)*(x+4)=0

=>x+9=0

or

=>x+4=0

Possible solutions:

x+9=0

=>x=-9 

x+4=0

=>x=-4
