Answer:6x^3+9x^1+12
Explanation:
First when we divide the x to the x to the 4th power. We do the rule of dividing exponent.
Next we keep the x then we subtract 4 by 1 which was equal to 3
Same as the we keep the x then we subtract 2 by 1.
Then if you divide 12x by x it will be 12
Which meant it is 6x^3+9x+12
