If the roots of equation `|(1,4,20),(1,-2,5),(1,2x,5x^2)|=0` are `alpha and beta` then

The roots of the equation |(1,4,20),(1,-2,5),(1,2x,5x^(2))|=0 are -

The roots of the equation |(1,4,20),(1,-2,5),(1,2x,5x^(2))| = 0 are

Determine the roots of the equation |(1,4,20),(1,-2,5),(1,2x,5x^(2))|=0.

If the roots of equation 5x^2-3x+6=0 are alpha and beta then find the value of 1/alpha+1/beta

The roots of the equation 2x^(2)-7x+5=0 are alpha and beta . Without solving the root find (1)/(alpha)+(1)/(beta)
