Question

solve (a-√3a)²+(a+√3a)²​

Answer 1

Step-by-step explanation:

(a-b)(a+b) = a^2-b^2

therefore in this sum

a^2- root 3 ^2

a^2- 3 a^2

therefore -2a^2is the answer.

Answer 2

Answer:

using identity :(a+b)²and (a-b) ²

{(a) ²+(√3a) ²-2(a)(√3a) } + {(a) ²+(√3a) ²+2(a)(√3a) }

={a²+3a²-2√3a²} + {a²+√3a² +2√3a²}

=a²+3a²-2√3a²+a²+3a²+2√3a²

=2a²+6a²

=8a²
