Question

(factorize using (a+b)2 and (a-b)2 using form
1. (p-q)2
2. a2-2a+1
3. y2+14y+49​

Answer 1

Answer:

1) p²-2pq+q²

2)(a-1)²

3) (y+7)²

Answer 2

Answer:

(p - q) 2

(a - b) 2

= A2 + b2 - 2ab

= P2 + q2 - 2pq

2). A2 - 2a + 1

= A2 - 2ab + b2 = (a - b) 2

= (a - 1) 2

= A2 - 2a× 1 + (1) 2

= A2 - 2a + 1

3) y2 + 14y + 49

A2 + 2ab + b2. = (a + b)2

= (y + 7) 2

= y2 + 49 + 14y
