Final Answer:

(3x²-10x²+7x+10) ÷ (3x+2) simplifies to (x-5)(3x+2).

Step-by-step explanation:

Here's the step-by-step simplification:

Identify the type of expression:

We have a polynomial expression divided by another polynomial expression.

Check for factoring opportunities:

Neither the numerator nor the denominator can be factored further.

Use polynomial division:

We can use polynomial long division or synthetic division to perform the division.

Polynomial Long Division:

x - 5

3x + 2 | 3x^2 - 10x^2 + 7x + 10

- (3x^2 + 2x)

------------

-12x^2 + 7x + 10

- ( -12x^2 - 8x )

------------

15x + 10

- ( 15x + 10 )

------------

0

Synthetic Division:

x - 5

3 2

3 -10 7 10

\ 9 -2 4

--------------------------

3 -1 5 14

Interpret the result:

The quotient obtained after the division is x - 5 and the remainder is 14. Therefore, the simplified expression is:

(3x²-10x²+7x+10) ÷ (3x+2) = x - 5 + 14 / (3x+2)

Since the remainder isn't zero, the final simplified form is:

(x - 5)(3x+2)
