Question

complete the quadratic equation whose roots are 1/3 and -2/5 ​

Answer 1

Answer:

Any quadratic equation is of the form $k(x^2-(\alpha +\beta )x+\alpha \beta )$

where $\alpha$ and $\beta$ are the roots of the polynomial

So substitute $\alpha$ = 1/3 and $\beta$ = -2/5 in above equation to get the answer. You can take any value of k.
