Question

if alpha and beta are the zeros of the given polynomial p(x) = 4x^2 - x - 4 . find alpha - beta
(class 10th maths chapter polynomial) ​

Answer 1

Answer:

(1+√65) /8, (1-√65) /8

Step-by-step explanation:

zeros of a quadratic equation of the form ax^2+bx+c=0 is given by x=(-b+√(b*b-4ac))/2a,(-b-√(b*b-4ac))/2a

substiting given a=4,b=-1,c=-4 we get alpha and beta
