If the locus of the point, whose distances from the point

(2,1)

and

(1,3)

are in the ratio

5: 4

, is

a x^2+b y^2+c x y+d x+e y+170=0

, then the value of

a^2+2 b+3 c+4 d+e

is equal to:

View answer and explanation

Correct option: C

Option C (37) is correct because it is the result of substituting the coefficients of the locus equation into the given expression after correctly deriving the locus equation.
