Question

If a and are the zeroes of the quadratic polynomial p(x)=4x2 – 5x-1, then

a)a²B+aB²=-5/16
b)a/b+b/a=17/4
c)1/a+1/b=-5
d)a²+B²=33/16​

Answer 1

Answer:

(A)

Step-by-step explanation:

a and b are the zeroes of 4x^2–5x+1=0…..(1)

a+b=5/4……………(2)

a.b=1/4………………(3)

Multiply eq.(2) and eq.(3)

a.b.(a+b)=5/4×1/4

a^2.b+a.b^2=5/16 ,Answer.
