Question

2. Simplify (7^t2 + 9) + (6^t2 + 8). (1 point)
t2 + 1
13t2 + 17
13t4 + 17
42t2 + 72

Answer 1

Okay, what's the first step?

Answer 2

im stuck on if i should combine like terms or add them, im guessing the answer is b or c

Answer 3

Well you're going to combine like terms and, in this case, you're only going to do addition. Let's start by dropping the parenthesis. Since you're not subtracting the two polynomials, you don't have to worry about something wacky happening.

So we've got:
\[7t ^{2} +9 + 6t ^{2}+8\]
Right?

Answer 4

okay so it would be 13^t2+17? o-o

Answer 5

Yep, you got it. :)

Answer 6

thanks :3!!
