we're being asked to perform the given operations on the polynomial negative to be to the fourth plus seven B minus three B to the fore. Essentially, they're just asking us to simplify this polynomial, which means we want to combine any like terms. Well are like terms in this case are negative to be to the fourth and negative three beats of the fourth. Well, using to community property. I can rearrange the order of my terms so we'll have negative to be to the fourth minus three B to the fourth and seven. B does not have a late term, so I will just bring that down plus seven b. So now let's go ahead and combine negative to be to the fourth by industry. Be to the fourth. Well, negative two minus three is negative. Five. So we'll have negative five be too before and again. Seven b does not have a late term, so that will just be brought down. So our final answer will be negative. Five b to the fourth plus seven
