I'll treat these like they're two seperate problems because how you set it up they're not together. If it's one whole problem please tell me and I'll solve it that way. :-)
First one: 3x+9+8x + 12
Collect like terms and simplify
(3x+8x)+(9+12)
11x+21
Second one: 2x + 6+x² + 6x + 9
Collect like terms and simplify
![(2x+6x)+(6+9)+x^{2}](https://tex.z-dn.net/?f=%282x%2B6x%29%2B%286%2B9%29%2Bx%5E%7B2%7D)
8x+15+![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
Hope this helps you, have a BLESSED and wonderful day, as well as a safe one!
