1.

if alpha and beta are two zeros ofpolynomial 2x2 -3x -5 then find the value of alpha + beta ÷ alpha +× beta

Answer»

Heya !!



2X² - 3X - 5




Here,


A = 2 , B = -3 and C = -5



Sum of zeroes = -B/A



ALPHA + BETA = 3/2




And,


PRODUCT of zeroes = C/A



Alpha × Beta = -5/2






Therefore,




Alpha + Beta / Alpha × Beta = 3/2 / -5/2



=> 3/2 × 2/ - 5




=> - 3/5.
