If a ^2 +b ^2 =c , then ^2 is equal to

Options

  1. Ab-c a-c
  2. Bc-b a-c
  3. Ca-c b-c
  4. Da-c c-b

Correct answer

B. c-b a-c

Step-by-step solution

a ^2 +b ^2 =c On dividing both sides by ^2 ^2 +b=c ^2 a ^2 +b=c (1+ ^2 ) a ^2 +b=c+c ^2 b=c+c ^2 -a ^2 (c-a) ^2 =(b-c) ^2 = b-c c-a or c-b a-c
