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.
