Question

Add: 3x+9+8x + 12 2x + 6+x² + 6x + 9

Answer 1

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

$(2x+6x)+(6+9)+x^{2}$

8x+15+$x^{2}$

Hope this helps you, have a BLESSED and wonderful day, as well as a safe one!
