Paragraph: Read the following information and answer that follow: Let a ^2 x+b ^2 x=c ; b ^2 y+a ^2 y=d and p x=q y . Question: What is ^2 x equal to ?

Step-by-step solution

aligned & From a ^2 x+b ^2 x=c & a ^2 x+b ^2 x=c ( ^2 x+ ^2 x ) & (a-c) ^2 x=(c-b) ^2 x & ^2 x ^2 x = (c-b) (a-c) & ^2 x= (c-b) (a-c) aligned
