Question

what must be subtracted from x3 - 6x2- 15x + 80 , so that the result is exactly divisible by x2 + x - 12 ??​

Answer 1

Answer:

we have to divide

x 3 - 6 {x}^{2} - 15x + 80x3−6x

2

−15x+80

by

x {}^{2} + x - 12x

2

+x−12

the reminder will be subtracted

from

x3 - 6 {x}^{2} - 15x + 80x3−6x

2

−15x+80

so the result will be exact
