2025 · 23 Jan · Shift 2 · Q47

JEE MainMathematicsParabolaNumerical+4 / −1
The focus of the parabola y2=4x+16y^2=4 x+16y2=4x+16 is the centre of the circle CCC of radius 5 . If the values of λ\lambdaλ, for which C passes through the point of intersection of the lines 3x−y=03 x-y=03x−y=0 and x+λy=4x+\lambda y=4x+λy=4, are λ1\lambda_1λ1​ and λ2,λ1<λ2\lambda_2, \lambda_1\lt \lambda_2λ2​,λ1​<λ2​, then 12λ1+29λ212 \lambda_1+29 \lambda_212λ1​+29λ2​ is equal to ‾\underline{\hspace{2cm}}​ .
