Answer 2

Answer:

If 4a-1 is a factor of polynomial then after dividing with 4a-1 remainder will be zero.

Steps to Divide the expression:

Step 1: Divide the dividend's lead term by divisor's lead term.

Step 2: This gives the first term of the quotient.

Step 3: Then multiply the divisor by the first term of the quotient and subtract the dividend from the product

Step 4: Put the next term down and repeat the above steps.

The required division is shown below:

Thus, remainder is -3 therefore 4a-1 is not the factor
