Answer:

Explanation:

To simplify the expression (12x^3 - 7x^2 + 24x + 26)/(4x + 3), we can use long division. Here are the steps:

1. Divide the first term of the numerator (12x^3) by the first term of the denominator (4x). The result is 3x^2.

2. Multiply the denominator (4x + 3) by the result obtained in step 1 (3x^2). The product is 12x^3 + 9x^2.

3. Subtract the product obtained in step 2 from the numerator (12x^3 - 7x^2 + 24x + 26) and write the result below.

12x^3 - 7x^2 + 24x + 26

- (12x^3 + 9x^2)

____________________

-16x^2 + 24x + 26

4. Bring down the next term from the numerator, which is 24x.

-16x^2 + 24x + 26

5. Divide the first term of the new expression (-16x^2) by the first term of the denominator (4x). The result is -4x.

6. Multiply the denominator (4x + 3) by the result obtained in step 5 (-4x). The product is -16x^2 - 12x.

7. Subtract the product obtained in step 6 from the new expression (-16x^2 + 24x + 26) and write the result below.

-16x^2 + 24x + 26

- (-16x^2 - 12x)

___________________

36x + 26

8. Bring down the last term from the numerator, which is 26.

36x + 26

9. Divide the first term of the new expression (36x) by the first term of the denominator (4x). The result is 9.

10. Multiply the denominator (4x + 3) by the result obtained in step 9 (9). The product is 36x + 27.

11. Subtract the product obtained in step 10 from the new expression (36x + 26) and write the result below.

36x + 26

- (36x + 27)

______________

-1

12. The remainder is -1.

Therefore, the simplified expression is 3x^2 - 4x + 9 - 1/(4x + 3).
