Question

7. What should be subtracted from 8x + 7 + 4x³ + 8x² to make it divisible by 2x² + 1?​

Answer 1

Answer:

You should divided the big equation by the small one and then you will get the quotient as

2 {x}^{2}-2

and remainder as

5x - 11

and the remainder must be subtracted so the answer is

5x - 11

Answer 2

Answer:

6x+3 should be substracted .

Step-by-step explanation:

4x³+8x²+8x+7

= 2x(2x²+1) +4(2x²+1) -2x -4 +8x+7

= (2x²+1)(2x+4) +6x+3

6x+3 should be substracted .
