If (alpha, beta) are the roots of the equation 15 x ^(2) - 22 x + 8=0 and (alpha', beta') are the roots of the equation 8x^(2) - 22x + 15=0, then the equation of the circle on A (alpha, alpha') and B (beta, beta') as diameter is

Answer»

`120 (x ^(2) + y ^(2)) - 22 ( 8X + 15y) + 289 =0`
`120 (x ^(2) + y ^(2)) - 22 ( 15 y + 8x) + 289 =0`
`23 (x ^(2) +y ^(2)) + 22 (8x + 15y ) - 120 =0`
none of these
