please give me answer

Step-by-step explanation:
1 :-
16x^2 - 81y^2 =
(4x)^2 - (9y) ^2
(4x+9y) (4x - 9y)
2 :-
4x^2y^2 - 25y^2 =
(2xy)^2 - (5y)^2 =
(2xy + 5y) (2xy - 5y)
3:-
x^4 - 16 =
(x^2)^2 - 4^2
= (x^2 + 4) (x^2 - 4)
4:-
9x^2 + 24x + 16
= 9x^2 + 12x + 12x + 16
= 3x (3x + 4) +4 (3x + 4)
= (3x+4) (3x+4)
= (3x+4)^2
5:-
4x^2y^2 - 4xyz + z^2 =
4x^2y^2 -2xyz -2xyz + z^2
= 2xy ( 2xy - z ) -z (2xy - z)
= (2xy-z) (2xy-z)
= (2xy-z)^2
6:-
x^2 / 36 - 49 =
(x/6)^2 - 7^2
(x/6 + 7) (x/6 - 7)
Answer:
Step-by-step explanation:
1 :-
16x^2 - 81y^2 =
(4x)^2 - (9y) ^2
(4x+9y) (4x - 9y)
2 :-
4x^2y^2 - 25y^2 =
(2xy)^2 - (5y)^2 =
(2xy + 5y) (2xy - 5y)
3:-
x^4 - 16 =
(x^2)^2 - 4^2
= (x^2 + 4) (x^2 - 4)
4:-
9x^2 + 24x + 16
= 9x^2 + 12x + 12x + 16
= 3x (3x + 4) +4 (3x + 4)
= (3x+4) (3x+4)
= (3x+4)^2
5:-
4x^2y^2 - 4xyz + z^2 =
4x^2y^2 -2xyz -2xyz + z^2
= 2xy ( 2xy - z ) -z (2xy - z)
= (2xy-z) (2xy-z)
= (2xy-z)^2
6:-
x^2 / 36 - 49 =
(x/6)^2 - 7^2
(x/6 + 7) (x/6 - 7)
