  • The identity used is:-

(x + a)(x + b) =  {x}^{2} + ( a + b ) x + a b 

Some other identities :-

1. {x+y}^{2} =  {x}^{2} + 2xy+  {y}^{2}

2. {x-y}^{2} =  {x}^{2}2xy +  {y}^{2}

3. {x}^{2} {y}^{2} = (x+y)(x-y)

4.(x+a)(x-b) =  {x}^{2} + (a+b)x+ab

5. {x+y+z}^{2} =  {x}^{2} +  {y}^{2} +  {z}^{2} + 2xy+2yz+2zx

6. {x+y}^{3} =  {x}^{3} +  {x}^{3} +3xy(x+y)

7. {x-y}^{3} =  {x}^{3} {y}^{3}3xy(x-y)

8. {x}^{3} +  {y}^{3} +  {z}^{3}-3xyz

= ( {x+y+z}) ( {x}^{2} + {y}^{2} +  {z}^{2} {xy-yz-zx)}
