Answer:
[tex]\boxed{\sf \ x = -12 \ \ or \ \ x=2 \ }[/tex]
Step-by-step explanation:
Hello,
[tex]x^2+10x+12=36\\<=>x^2+10x+12-36=0<=>x^2+10x-24=0[/tex]
[tex]<=> x^2-2x+12x-24=0\\<=>x(x-2)+12(x-2)=0\\<=>(x+12)(x-2)=0\\<=> x = -12 \ or \ x=2[/tex]
Do not hesitate if you need further explanation
hope this helps
