Answer:
α+ß=(√5/3)+(-√5/3)=√5/3-√5/3=0=-co-efficient of x/co-efficient of x^2
αß=(√5/3)*(-√5/3)=[(-√5)^2/3^2]=-5/9=constant/co-efficient of x^2
Step-by-step explanation:
9x^2-5=0
9x^2=5
x^2=5/9
x=√(5/9)
x=√5/3
x=+√5/3,-√5/3
α=+√5/3,ß=√5/3
α+ß=(√5/3)+(-√5/3)=√5/3-√5/3=0=-co-efficient of x/co-efficient of x^2
αß=(√5/3)*(-√5/3)=[(-√5)^2/3^2]=-5/9=constant/co-efficient of x^2
I hope this helps you.
