Question

6. Write all the identities for factorisation​

Answer 1

Step-by-step explanation:

Identity I: (a + b)2 = a2 + 2ab + b2

Identity II: (a – b)2 = a2 – 2ab + b2

Identity III: a2 – b2= (a + b)(a – b)

Identity IV: (x + a)(x + b) = x2 + (a + b) x + ab

Answer 2

Answer:

1) a2 + 2ab + b2 = (a + b)2

2) a2 – 2ab + b2 = (a – b)2

3) a2 – b2 = (a + b) (a – b)

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