Question

if alpha and bita are zeros of the quadratic polynomial p(x)=ax^2+bx+c,then evaluate alpha-bita

Answer 1

Hey mate here is your answer,
according to question,a+ b=-b/a
ab=c/a
so value of a-b=√(a+b)2-4ab
putting given values,
a-b=√b2/a2-4c/a
a-b=√b2/a2-4c/a
a-b=√b2-4ca/a2
Hope it will be helpful for you
