Question

Which are the eight identities of polynomial?​

Answer 1

Answer:

Step-by-step explanation:

1) ( x + y )2 = x2 + 2xy +y2

2) ( x – y) 2 = x2 – 2xy + y2

3) (x + y)(x – y) = x2 – y2

4) (x + a)(x + b) = x2 +(a + b)x + ab.

5) (x + y) 3 = x3 + 3x2y + 3xy2 + y3 = x3 + y3 +3xy(x +y)

6) (x - y) 3 = x3 - 3x2y + 3xy2 - y3 = x3+ y3 -3xy(x –y)
