Question

If alpha and beta are the roots of the quadratic equation y square - 2y - 7 is = to 0 then Alpha square + beta square is equals to?

Answer 1

Answer:

Step-by-step explanation:

First find the discriminant (d)=44

By quadratic formula method

Y = 1+√11. Or. Y= 1-√11

Substituting this value you will get

Alpha square + beta square = 24
