Q. 1 G5.0( 1 Vote )

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

78x4; –7x2

Answer :

The division is as follows:

Here when -7x2 is multiplied by -4x2 we get -28x4 as the result.

Here the divisor is negative so the quotient has to be negative to get remainder zero.

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 -28x4 becomes perfectly divisible by -7x2 and hence the quotient is -4x2 and remainder is 0.
