Divide the first polynomial by the second. Explain the steps.

15m³; 5m

The division is as follows:

Here when 5m is multiplied by 3m² we get 15m³ as the result.

In division the sign of the product [divisor × quotient] is always inverted to get the final result.

So the sign of product should always be opposite to that of the dividend.

So 15m³ becomes perfectly divisible by 5m and hence the quotient is 3m² and remainder is 0.
