If `x+4y=14` is a normal to the curve `y^2=alphax^3-beta` at (2,3), then the value of `alpha+beta` is 9 (b) `-5` (c) 7 (d) `-7`

If alpha+ beta=-7 and alpha beta=10 then find the value of alpha-beta=__ .

If 2|sin2alpha|=|tanbeta+cotbeta|,alpha,beta in (pi/2,pi), then the value of alpha+beta is (a) (3pi)/4 (b) pi (c) (3pi)/2 (d) (5pi)/4

If g={(1, 1), (2, 3), (3, 5), (4, 7)} is a function given by g(x)=alphax+beta then the values of alpha and beta are

If parabolas y^2=lambdax and 25[(x-3)^2+(y+2)^2]=(3x-4y-2)^2 are equal, then the value of lambda is (a)9 (b) 3 (c) 7 (d) 6

If alpha and beta are the roots of quadratic equation 2x^(2)+4x+3=0 , then the value of alpha+beta= A)-2 B)2 C)34 D)-4

If alpha and beta are the roots of 2x^(2) – 3x -4 = 0 find the value of 2 alpha^(2)+ beta^(2)

If alpha" and "beta are the roots of the quadratic equation 4x^(2)+3x+7=0 , then the value of (1)/(alpha)+(1)/(beta)=
