Question

find the remainder when 2x^4-3x^2-7x+5 is divided by x^2-4​

Answer 1

Step-by-step explanation:

1. Divide 2x^4 by x^2 which gives 2x^2 as quotient.
2. then multiply -4 with 2x^2 which gives -8x^2.
3. minus it with the divident.
4. and repeat this process till the remainder variable is less than the divisor i.e (-7x+25) has less power of x than the divisor.

Note: When dividing the divident with divisor be sure that you have put 2x^4 with same variable x^4.
