you can find it in two ways the first one is that you can the roots by solving this equation and you can put their values i will tell you the second one
α+β=3 and αβ=-10
you need to find α^2+β^2
you can also write it as (α+β)^2-2αβ
by putting the value of α+β and αβ
we have
3^2-2*-10=29
Hope it will help you
