Question

Check my answer? Will Medal.

Answer 1

Add (7x6 + 10x2 − 10) + (3x6 − 6x3 + 4).

10x6 + 4x2 − 6
10x6 + 4x3 − 6
10x6 − 6x3 + 10x2 − 6 <---- I chose C.
10x6 + 10x2 − 6x3 + 6

Answer 2

Or wait I think I know what I did wrong, It would be D wouldn't it?

Answer 3

7x^6 + 10x^2 - 10 + 3x^6 - 6x^3 + 4 -- parenthesis are not needed if it is separated by a + sign.

now we combine like terms...but don't forget about the number if there is no like term.
7x^6 + 3x^6 = 10x^6
-6x^3 -- there is no other like term with this
10x^2 -- there is no other like term with this
-10 + 4 = -6

now put it all together
10x^6 - 6x^3 + 10x^2 - 6 ---- you were correct the first time...it is C

Answer 4

Answer 7

Yeah I see it. I flipped the signs the second time, which made me think I had it wrong.
