Question

if alfa and beta are roots if the quadratic equation 2x2+6x-5=0then find alfe+beta and alfa beta​

Answer 1

Answer:

Step-by-step explanation:

consider the equation ax^2+bx+c=0

now sum of roots=-b/a

product of roots=c/a

given 2x^2+6x-5=0

and let a and b are roots

a+b=-6/2=-3

ab=-5/2
