Question

If sum of the roots of a quadratic equation is 30 and product of the roots is -5, then quadratic equation is___​

Answer 1

You need to learn this... after u learn, this will be very easy
f(x)=k[x^2 - (sum of roots)x + product of roots]
here, k is any constant.
Here lets pit the values of sum and product
f(x) = k(x^2 - 30x - 5)
Now, what about k? We can put value of k 1 here
so, f(x) = x^2 - 30x - 5
