Answer:
3x^2+14x-2 if you meant f(x)=3x^2+10x and g(x)=4x-2
and I think C was meant to read 3x^2+14x-2
Please correct me if I have mistranslated. Thank you kindly.
Step-by-step explanation:
I kind of wonder if you meant f(x)=3x^2+10x and g(x)=4x-2.
(f+g)(x)=f(x)+g(x)
=(3x^2+10x)+(4x-2)
=3x^2+10x+4x-2
=3x^2+(10x+4x)-2 I paired 10x and 4x together because they are like terms
=3x^2+14x-2
