a)

✬ Question :-

Add:  $p^{2} - 7pq - q^{2}$   and $- 3p^{2} - 2pq+7q^{2}$

✬ Answer :-  

  ✧ Step 1

$=p^{2} - 7pq - q^{2} + (- 3p^{2}) - 2pq+7q^{2}$

$=p^{2} - 7pq - q^{2} - 3p^{2} - 2pq+7q^{2}$

  ✧ Step 2 : We group the like terms together,

$=p^{2} - 3p^{2}- 7pq - 2pq- q^{2} +7q^{2}$

  ✧ Step 3 : And add,

$=- 2p^{2}- 9pq +6q^{2}$

✬ Solution :-

$\huge=- 2p^{2}- 9pq +6q^{2}$

B)

✬Question :-

Add :-

$x^{3} - x^{2}y - xy ^{2} - y^{3}$ and $x^{3} - 2x^{2}y +3xy^{2} + 4y$

✬ Answer :-

✧ Step 1

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

✧ Step 2 : We combine the like terms together,

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

✧ Step 3 : Then we add and get,

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

✬ Solution :-

$\huge {2x^{3} - 3x^{2}y +2xy^{2} - y^{3} + 4y}}$

c)

✬ Question:-

Add :

$ab + bc + ca$  and  $- bc - ca - ab$

✬ Answer :-

✧ Step 1

$=ab + bc + ca +(- bc) - ca - ab$

✧ Step 2 : We group the like terms together,

$ab - ab + bc - bc + ca - ca$

✧ Step 3 Upon adding, we get,

$(0)ab +(0) bc + (0) ca$

$= 0$

✬ Solution :-

$0$

Hope i helped mate ..!! :)
