: I need help solving some very complex problems that I do not understand.
Add
(9+4x+8^2+2x^3)+(9-4x+8x^2-2x^3)
Divide
14x^4-56x^3+49x/7x
Multiply
(7x-4)(x-6)
Subtract
(3x^4+5x^3-8)-(3x^2-6x+3)
Thank you in advance for whatever help you are able to give me This question is from textbook

Just combine like terms. So...
+%289%2B4x%2B8%5E2%2B2x%5E3%29%2B%289-4x%2B8x%5E2-2x%5E3%29=8x%5E2%2B18+
To divide, just put them over each other like....
+14x%5E4%2F7x+-56x%5E3%2F7x%2B49x%2F7x+=+2x%5E3-8x%5E2%2B7+
For multiplying, use the FOIL method (First numbers, Outside numbers, Inside numbers, and Last numbers).
+%287x-4%29%28x-6%29+=+7x%5E2%2B42x-4x%2B24+=+7x%5E2%2B38x%2B24+
Again, combine like terms for subtracting and adding... However, change the subtraction sign to addition and all the numbers after it to their opposite.

Good Luck and I hope this helped.
