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? –2yz2 – 4y 7 –2yz2 – 3y 1 –5yz2 3z2 – 3y 1 3yz2 – 3z2 – 5y 7.

Answer 1

The other polynomial is $\rm 3yz^2-3z^2-5y+7$ .

Given

The sum of two polynomials is –yz2 – 3z2 – 4y 4.

If one of the polynomials is y – 4yz2 – 3.

How to find the sum of two polynomials?

The sum of two polynomial is given by;

$\rm Sum \ of \ polynomial=First \ polynomial+Second \ polynomial$

Therefore,

The other polynomial is;

$\rm Sum \ of \ polynomial=First \ polynomial+Second \ polynomial\\\\ -yz^2 - 3z^2 - 4y^ 4= y -4yz^2 -3+Second \ polynomial\\\\Second \ polynomial= -yz^2 - 3z^2 - 4y^ 4-y+4yz^2+3\\\\Second \ polynomial= 3yz^2-3z^2-5y+7$

Hence, the other polynomial is $\rm 3yz^2-3z^2-5y+7$.
