Question

from the sum of 2 y square + 3 y z minus y square minus y z - Z Square and Y Z plus to 2Z Square subtract the sum of 3 y square minus Z Square and minus y square + Y Z + Z Square?<br />please answer the question.its urgent yaar​

Answer 1

Given:

$2 {y}^{2} + 3yz - {y}^{2} - yz - {z}^{2} - - (1)$

and

$yz + 2 {z}^{2} - (3 {y}^{2} - {z}^{2} - {y}^{2} + yz + {z}^{2} ) - - (2)$

equation (1) will be:

${y}^{2} + 2yz - {z}^{2}$

and equation (2) will be :

$2 {z}^{2} - 2 {y}^{2}$

on adding both the equations we get,

$2yz- {y}^{2} +3 {z}^{2}$
