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

Answer:

-3yz2-3z2-4y+7

Step-by-step explanation:

to get the other polynomial we have to subtract first polynomial from the sum.Therefore,

-yz2 -3z2-4y+4

-4yz2 -3

+ +=sign changes in subtraction

-3yz2-3z2-4y+7=answer
