I have answered both your question no. 6 and 7.
In the first attachment q no. 6's answer is there and in the second attachment q no. 7's answer is there.
Algebraic Identities used in q no. 7:-
1)I took - sign as common and then used (a + b whole square is equals to a square + b square + 2ab) and then (a square minus b square is equals to (a + b) (a minus b ).
2)I took 16 X cube as common out of the equation and then used (a square minus b square is equals to( a + b)( a minus b ).
3)I used the algebraic identity of (a minus b whole square is equals to a square + b square minus 2 a b ).
4)I used middle term factorisation.
