Answer 1

@master50777 please help I get how to do it but this question is a bit more confusing

Answer 2

since it is multiple choice, you can simplify each of your answers and see if you 3x^2 + 10x + 8

Answer 3

Yeah but none of them add up to 10

Answer 4

Notice how it is 3x^2, not x^2. You can add, but you have to multiply one of them by 3

Answer 5

So is it C? @master50777
