Are you guessing? What made you think your first response wasn’t correct?

Answer 3

First, let's simplify the fraction (8x^3-12x^2+18x-27)/(2x-3):

Using polynomial long division, we divide 8x^3-12x^2+18x-27 by 2x-3:

4x^2 - 1
________________
2x - 3 | 8x^3 - 12x^2 + 18x - 27
- (8x^3 - 12x^2)
________________
0 - 0 + 18x - 27
- (0 - 0 + 18x - 27)
________________
0

Therefore, (8x^3-12x^2+18x-27)/(2x-3) simplifies to 4x^2 - 1.

Now, we can rewrite the expression as (4x^2 - 1) - x^2 + 4x:

Combining like terms, we have 4x^2 - x^2 + 4x - 1:

This simplifies to 3x^2 + 4x - 1.

Therefore, the simplified form of (8x^3-12x^2+18x-27)/(2x-3)-x^2+4x is 3x^2 + 4x - 1.

Answer 4

Apologies for the mistake in my previous response. Let's redo the simplification.

We have the expression (8x^3-12x^2+18x-27)/(2x-3)-x^2+4x.

First, let's simplify the fraction (8x^3-12x^2+18x-27)/(2x-3) using polynomial long division:

4x^2 + 2x + 8
____________________
2x - 3 | 8x^3 - 12x^2 + 18x - 27
- (8x^3 - 12x^2)
____________________
0 + 30x - 27
- (0 - 6x + 9)
____________________
36x - 36
- (36x - 54)
____________________
18

Therefore, (8x^3-12x^2+18x-27)/(2x-3) simplifies to 4x^2 + 2x + 8.

Now, we can rewrite the expression as (4x^2 + 2x + 8) - x^2 + 4x:

Combining like terms, we have 3x^2 + 6x + 8.

Therefore, the simplified form of (8x^3-12x^2+18x-27)/(2x-3)-x^2+4x is 3x^2 + 6x + 8.

Answer 5

Apologies for the confusion caused by the incorrect first response.

To clarify, let's simplify the expression again:
(8x^3 - 12x^2 + 18x - 27)/(2x - 3) - x^2 + 4x

First, let's simplify the fraction (8x^3 - 12x^2 + 18x - 27)/(2x - 3):

Using polynomial long division or synthetic division, we find that the quotient is 4x^2 - 2x - 9, with a remainder of 0. Therefore, (8x^3 - 12x^2 + 18x - 27)/(2x - 3) simplifies to 4x^2 - 2x - 9.

Now, let's rewrite the expression as 4x^2 - 2x - 9 - x^2 + 4x:

Combining like terms, we have 3x^2 + 2x - 9.

Therefore, the simplified form of (8x^3 - 12x^2 + 18x - 27)/(2x - 3) - x^2 + 4x is 3x^2 + 2x - 9.
