Question

Factorise using suitable identities. (i) (a – b)^2 + 4ab (ii) m^2 - 256

Answer 1

Answer:

(i) (a + b)^2 (ii) (m - 16)(m + 16)

Step-by-step explanation:

(i) (a - b)^2 - 4ab

a^2 - 2ab + b^2 + 4ab

a^2 + b^2 - 2ab + 4ab

a^2 + b^2 + 2ab

(a + b)^2

(ii) m^2 - 256

(m)^2 - (16)^2

(m - 16)(m + 16)
