Divide the polynomials. Express numbers using integers or simplified fractions. Check your answer by multiplication.

(6m^4n^5 - 6m^3n^4 - 2m^2 - 7) / (m^2n)

To divide the given polynomials, we will use the long division method.

6m^2n^4 - 6mn^3 - 2n - 7/m

We start by dividing the first term of the dividend, 6m^4n^5, by the divisor m^2n:

________
m^2n | 6m^4n^5 - 6m^3n^4 - 2m^2 - 7

6m^2n^4

Next, we multiply this quotient, 6m^2n^4, by the divisor m^2n, and subtract it from the dividend:

6m^4n^5 - 6m^3n^4 - 2m^2 - 7
- (6m^2n^4)

----------------------
- 6m^2n^5 + 6m^3n^4 - 2m^2 - 7

We repeat this process with the remaining terms:

___________________
m^2n | 6m^4n^5 - 6m^3n^4 - 2m^2 - 7

+ - 6m^2n^5

___________________
+ - 6m^2n^5 + 6m^3n^4

+ 6m^3n^4

___________________
+ 6m^3n^4 - 2m^2

+ 2m^2

___________________
+ 2m^2 - 7

+ 7

Now, we have fully divided the dividend by the divisor.

Therefore, the division expression is:

(6m^4n^5 - 6m^3n^4 - 2m^2 - 7) / (m^2n) = 6m^2n^4 + 6m^3n^3 + 2m^2 + (2m^2 - 7) / (m^2n)

To check our answer, we can multiply the divisor by our quotient:

(m^2n)(6m^2n^4 + 6m^3n^3 + 2m^2) + (m^2n)(2m^2 - 7)

= 6m^4n^5 + 6m^5n^4 + 2m^4n^2 + 2m^4n - 7m^2n

= 6m^4n^5 + 6m^5n^4 + 2m^4n^2 + 2m^4n - 7m^2n

Our answer is verified by multiplication.
