Question

Simplify the sum.

(2u3 + 6u2 + 3) + (2u3 – 7u + 6)
A. 9 – 7u + 6u2 + 4u3

B. 0u3 + 6u2 – 7u + 9

C. 0u3 – 7u2 + 6u – 9

D. 4u3 + 6u2 – 7u + 9

Answer 1

Unless it is more complicated than it look, it is very simple. All you have to do is add the common terms...2u3+2u3=4u3
6u2 has no common term, so leave it, -7u has no common terms, and 3+6=9
so your answer is 4u3+6u2-7u+9
