Question

The sum of two polynomials is –yz2 – 3z2 – 4y + 4. If one of the polynomials is y – 4yz2 – 3, what is the other polynomial?

Answer 1

sum of two polynomials is –yz2 – 3z2 – 4y + 4 (1)

one polynomial is y+4yz2+3 (2)

we need to find second polynomial.

we subtract equation(2) from equation(1).

-yz2-3z2-4y+4-(y+4yz2+3)= 3yz2-5y-3z2+7

Answer 2

it is d 3yz2 – 3z2 – 5y + 7
