Answer

6x - 9 Explanation 1. Set up the division Divide 24x^4 by 4x^3 to get 6x. Multiply (4x^3 + 2x^2) by 6x and subtract from the original polynomial. 2. Perform subtraction Subtract (24x^4 + 12x^3) from (24x^4 - 24x^3 - 18x^2) to get -36x^3 - 18x^2. 3. Repeat division Divide -36x^3 by 4x^3 to get -9. Multiply (4x^3 + 2x^2) by -9 and subtract. 4. Final subtraction Subtract (-36x^3 - 18x^2) from (-36x^3 - 18x^2) to get 0.

Explanation

1. Set up the division<br /> Divide $24x^4$ by $4x^3$ to get $6x$. Multiply $(4x^3 + 2x^2)$ by $6x$ and subtract from the original polynomial.<br />2. Perform subtraction<br /> Subtract $(24x^4 + 12x^3)$ from $(24x^4 - 24x^3 - 18x^2)$ to get $-36x^3 - 18x^2$.<br />3. Repeat division<br /> Divide $-36x^3$ by $4x^3$ to get $-9$. Multiply $(4x^3 + 2x^2)$ by $-9$ and subtract.<br />4. Final subtraction<br /> Subtract $(-36x^3 - 18x^2)$ from $(-36x^3 - 18x^2)$ to get $0$.
