Question

If you will answer it wrong then i will report solution​

Answer 1

Answer:

Let the required polynomial be p(x).

According to question,
p(x) + (4x^3+7x+8) = 4x^3 + 5x^2+x+15

Subtracting 4x^3+7x+8 on both sides,
p(x) = 4x^3+5x^2+x+15 - 4x^3 - 7x - 8

     = 5x^2-6x +7
This is the required polynomial.

Answer 2

5x² - 6x + 7 should be added to 4x³ + 7x + 8

Justification :

Given that ;

Polynomial :

4x³ + 7x + 8

Result Polynomial :

4x³ + 5x² + x + 15

Asked That ;

Which Polynomial should be added ?

Hence ,

Subtract Resulting Polynomial from given Polynomial :

( 4x³ + 5x² + x + 15 ) - ( 4x³ + 7x + 8 )

5x² - 6x + 7

So ,

5x² - 6x + 7 is the required Polynomial .
