Answer 2

Hey Mate,

I will solve your question part-wise.

16 ) a )

Given Terms to Add,

7xy + 5yz - 3zx, 4yz + 9zx - 4y, -3xz + 5x - 2xy

= ( 7xy + 5yz - 3zx ) + ( 4yz + 9zx - 4y ) + ( -3xz + 5x - 2xy )

= 7xy + 5yz - 3zx + 4yz + 9zx - 4y - 3xz + 5x - 2xy

= 7xy - 2xy + 5yz + 4yz - 3zx + 9zx - 3zx - 4y + 5x

= 5xy + 9yz + 3zx - 4y + 5x

Therefore, your final answer is :-

5xy + 9yz + 3zx - 4y + 5x

16 ) b )

Given Terms to Subtract,

$5x^{2} - 4y^{2} + 6y - 3, 7x^{2} - 4xy + 8y^{2} + 5x - 3y$

= $( 7x^{2} - 4xy + 8y^{2} + 5x - 3y ) - ( 5x^{2} - 4y^{2} + 6y - 3 )$

= $7x^{2} - 4xy + 8y^{2} + 5x - 3y - 5x^{2} + 4y^{2} - 6y + 3$

= $7x^{2} - 5x^{2}  + 8y^{2} + 4y^{2} - 4xy + 5x - 3y - 6y + 3$

= $2x^{2}  + 12y^{2}  - 4xy + 5x - 9y + 3$

Therefore, your final answer is :-

$2x^{2}  + 12y^{2}  - 4xy + 5x - 9y + 3$

Hope it Helps!
