यदि `(1+x-2x^(2))^(6)=1+a_(1)x+a_(2)x^(2)+...+a_(12)x^(12)`, तो दिखलाइए कि `a_(2)+a_(4)+a_(6)+...+a_(12)=31`

If (1+x-2 x^(2))^(6)=1+a_(1) x+a_(z) x^(2)+l .. .+a_(12) x^(12) then a_(2)+a_(4)+..+a_(12) =

If (1+x-2x^(2))^(6)=1+a_(1)x+a_(2)x^(12)+...+a_(12)x^(12) then find the value of a_(2)+a_(4)+a_(6)+...+a_(12)

(1+x-2x^(2))^(6)=1+a_(1),x+a_(2)x^(2)+….+a_(12)^(12) then the value of a_(2) +a_(4)+a_(6)+….+a_(12)=………

If (1+x-2x^2)^(6) = 1 + a_(1) x + a_(2) x^(2) + ... + a_(12) x^(12) , then find a_2+ a_4 + ... + a_12

If (1+x-2x^(2))^(6)=1+a_(1)x+a_(2)x^(2)+….+a_(12)^(x^(12)) , then find the value of a_(2)+a_(4)+a_(6)+….+a_(12) .

(1+x-2x^(2))^(6)=1+a_(1)x+a_(2)x^(2)+a_(2)x^(3)+....., then the value of a_(2)+a_(4)+a_(6)+......+a_(12) will be (a) 32 (b) 31 (c) 64 (d) 1024

If (1+x-2x^(2))^(6) = 1 + a_(1)x+a_(2)x^(2) + "……" + a_(12)x^(12) , then find the value of a_(2) + a_(4) +a_(6)+ "……" + a_(12) .
