Answer:

The answer to your question is 2x² + 3x +  Remainder (17x - 7)/ ( 2x⁴  +  3x³  - 4x²  + 5x - 7)

Step-by-step explanation:

                             2x² + 3x

             x² - 4     2x⁴  +  3x³  - 4x²  + 5x - 7

                          -2x⁴              + 4x²

                            0      + 3x³   + 0    + 5x

                                     - 3x³             +12x

                                        0                +17x - 7

Quotient = 2x² + 3x

Remainder = 17x - 7

Solution  = 2x² + 3x + (17x - 7)/ ( 2x⁴  +  3x³  - 4x²  + 5x - 7)

Process

1.- Divide the first term of the divident by the first term of the divisor and place the result above the first term of the divident.

2.- Multiply the result of the division (2x²) by the first term of the divisor and change the sign of the result.

3.- Multiply the result (2x²) by the second term of the divisor and place the result below the like term.

4.- Add the results.

5.- Continue with this process until the remainder be lower than the divisor.
