Question

If alpha, beta be the roots of x^2 - 5x + 43.
Find alpha × beta / alpha^2 + beta^2

Please answer this.​

Answer 1

ans,:

alpha×beta formula is c/a

alpha+beta formula is -b/a

find the values

alpha×beta = 43

alpha+beta is 5

do alpha +betahole suare and subtract 2ab

a²+b²+2ab-2ab=5

then à²+b²=-71 and ab is 43 so and is -43/71
