Perform the indicated operation and simplify if possible by combining like terms. Write the result in standard form.
(4w^3 − 3w + 8) + (5w^3 + 6w^2 − 1)

can anyone help me figure this out?

I don't remember much of algebra except you multiple to first number by all the ones in the second parenthesis, then the second number by the number in the right parenthesis, then the 3rd then put them together, correct? I havent taken algebra in a few years and haven't had college yet. but I'll give it a shot

I got 20w^6+9w^4+18w^3+48w^2+3w-8

Thanks:) Oh how I miss math. I don't have to take algebra for my degree.
But when multiplying with ^# you multiple the number before the variable, then add the power. then run all of them and add or subract them together using the +/- infront of them.

(4w^3 − 3w + 8) + (5w^3 + 6w^2 − 1)

can anyone help me figure this out?

It's 9w^3 + 6w^2 - 3w + 7.

You are just adding the like terms, not multiplying anything. Pretty simple.

Awe crap, Carrot is right, I did it as if the + sign wasnt there. I did it as if it was (4w^3 − 3w + 8) (5w^3 + 6w^2 − 1)
Sorry bud

Possible I'm glad you figured out what you did wrong. I read your first answer, and I was like "Is this guy fucking stupid?" xD

Nope. It would be 20w^6 + 24w^5 - 15w^4 + 18w^3 + 48w^2 + 3w - 8.
