a * b = a^2+b^2 হলে 2*4 এর মান | শ্রেণী 12 | নেই | গণিত | ডাউটনাট

If a + b = 12 an 2ab = 32, then a^2 + b^2 = ?

Common factor of 12 a^(2) b ^(2) + 4 ab ^(2) - 32 is .

If (a + b) = 12 and ab = 14, then (a^(2) + b^(2)) = ?

Find the value of ( a^2/b^2 + b^2/a^2 ) is ( a ) ( a/b + b/a )^2 - 2 ( b ) ( a/b + b/a )^2 + 2 ( c ) ( a/b + b/a )^2 + 4 ( d ) ( a/b + b/a )^2 - 4

Factorise the using the identity a ^(2) + 2 ab + b ^(2) = (a + b) ^(2) 4x ^(4) + 12 x ^(3) + 9x ^(2)

Subtract the sum of 12ab-10b^2 -18a^2 and 9ab + 12 b^2+ 14a^2 " from the sum of " ab + 2b^2 and 3b^2-a^2 .

If a^(4) + a^(2)b^(2) + b^(4) = 12, a^(2) + ab+ b^(2)=4 , find ab

Factorise the using the identity a ^(2) + 2 ab + b ^(2) = (a + b) ^(2) 4x ^(2) + 12 x + 9

Factorise the using the identity a ^(2) - 2 ab + b ^(2) = (a -b) ^(2). 4y ^(2) - 12 y + 9
