Question

FACTORISE:
16a^2 + 4b^2+9c^2- 16ab+12bc - 34ac​

Answer 1

By using (a+b+c)^2= a^2+b^2+c^2+2ab+2bc+2ca

We get,
Root 16a^2 +Root4b^2+Root9c^2

(because in the question the squares of 4a,2b,3c are solved and is given 16a^2,4b^2 and 9c^2)

(4a+2b+3c)

(because powers are equal; so taken as common power)
