Question

If equation 2x^2−7x+12=0 has two roots α and β, then the value of α/β+β/α is,​

Answer 1

Answer:

alpha /Bita + Bita/ Alpha

= alpha^2+ Bita ^2/ alpha. Bita

= (alpha+ Bita)^2 - 2.alpha.Bita/ alpha. Bita

= (-b/a)^2 - 2 .c/a/c/a

=49/4-12/6

=1/4/6

=1/24........

Hope it will help you......

Answer 2

Then after this, u can put the values by taking LCM....
