Question

What must be added to 3x³ + x² – 22x + 9 so that the result is exactly divisible by 3x² + 7x - 6.Give the whole soln

Answer 1

I hope it will help you

Answer 2

Step-by-step explanation:

Let us divide 3x3+x2−22x+9 by 3x2+7x−6 by long division method as shown in the above image.

Therefore, the the remainder is −2x−3 that is −(2x+3)

Hence, −(2x+3) must be subtracted from 3x3+x2−22x+9 that is (2x+3) must be added to 3x3+x2−22x+9 so that the resulting polynomial is exactly divisible by 3x2+7x−6................
