Divide. x^4 + x^2 - 80 from x+3. I get stuck on the +3 part of the division.
:
Remember each degree has to be represented: (using "..." to get things line up)
:
.........................x^3 - 3x^2 +10x - 9
...........-----------------------------
(x+3) | x^4 + 0x^3 + x^2 + 0x - 80
..............x^4 + 3x^2
.............----------
......................- 3x^3 + x^2
......................- 3x^3 - 9x^2
......................------------
................................10x^2 + 0x
................................10x^2 + 30x
