In ABC , a^2 2 B+b^2 2 A=

Options

  1. A2 a b ~A
  2. B2 a b ~A
  3. C2 a b C
  4. D2 a b C

Correct answer

C. 2 a b C

Step-by-step solution

We know that aligned & a A = b B = c C =K & a=K A, b=K B, c=K C & a^2 2 B+b^2 2 A & =K^2 [ ^2 A 2 B B+ ^2 B 2 A A ] & =2 K^2 A B[ A B+ A B] & =2 a b (A+B)=2 a b ( -C)=2 a b C aligned
