Answer:
let alpha be x and beta be y
Step-by-step explanation:
x+y= -b/a
x+y=-1/6
and xy= c/a
xy= -1/3
according to question
1/x+1/y -xy =(x+y)/xy-xy
(-1/6)/(-1/3)-(-1/3)
1/2+1/3
the answer is 5/6
Answer:
Step-by-step explanation:
Given equation to us is ,
So , a equation is said to be a quadratic equation if the highest degree of the variable is 2 . On simplifying the Equation ,
Taking x as LCM ,
Transposing x to RHS .
Putting all terms in LHS
Since here the highest degree of the variable is 3 not 2 . So its a cubic equation and not a quadratic equation .
