Question

Raj correctly subtracted a polynomial from 2x ^ { 2 } -9y+3xy-8. The answer he got was 7x ^ { 2 } +5y-8Which is the polynomial he subtracted?

Answer 1

Step-by-step explanation:

10−14x

4x2+3x−2)8x4+14x3−2x2+7x−8 ( 2x2+2x−1

                          −8x4−+6x3+−4x2

                                     8x3+2x2+7x−8

                                     −8x3−+6x2+−4x

                                             −4x2+11x−8

                                             +−4x2+−3x−+2

                                                          14x−10

We have to add 10−14x so that 8x4+14x3−2x2+
