Answer 1

Answer:

2. Simplify:

(a) (3a + 5b) (3a - 5b) - (a - b)2 + (2a + b)2.

(b) (5x + 7y) (5x – 7y) + (x + 2y)2.

(C) (9x + 4y) (9x - 4y) – (3x + 2y)2.

id) (4x + 7y) (4x - 7y) - (4x – 3y2

e) (6x + 5y)2 - Y6 + 5y) (6x - 5y) + (6x - 5y)2

(3a + 2b) (3a + 2b) – (4a – 3b)2 + (2a + 3b) (20 – 3b).

(g) (4a - 3b)2 + (4a + 3b)2.

(h) (x + y)2 - (x - y)2.

(i) (x + 3y)2 - (x - 3y)2.

0) (4x + 3y)2 + (4x - 3y)2

(k) (5x + 7y)2 – (5x + 7y) (5x -7y) - (5x – 7y)2

() (3x + 4y)2 - (3x + 4y) (3x - 4y) - (5x - 7y)2.

sorry bro I don't know this answer so sorry OK dear
