Step-by-step explanation:
SO IN THIS QUESTION WE HAVE TO PROVE THAT (A^2-B^2) = (A+B)(A-B)
WHICH MEANS ........ A square minus B square equals A plus B whole into A minus B
therefore ......
by putting the values of question no.3 that is ...
a=6p and b=5q
just put the values .....
(6p^2-5q^2) = (6p+5q) ( 6p-5q)
therefore...
break at the left hand side...
that is a square and b square
your equation will come the same after breaking A square and B square....
hence LHS= RHS....
now comes question no.5....
a=3x-4
b=4.2x
therefore by using the same method....
(3x-4 + 4.2x) (3x-4- 4.2 x)
(3x +4.2x -4) ( 3x-4.2x -4)
(7.2x-4) ( -1.2x -4)
on the L.H.S side.....it will be the same .....
that is ......
(7.2x-4) ( -1.2x -4)
