Question

if p and q be the zeroes of the polynomials x^2-5x+2, what is the value of 1/p+1/q-3pq

Answer 1

Answer:

Step-by-step explanation:

X²-5x+2

a= 1 b=-5 c= 2

Sum of zeroes (p+q)= -b/a = 5

Product of zeroes (pq)= c/a= 2

1/p+1/q-3pq

= (P+q)/pq -3pq

= 5/2-3(2)

=5/2-6

= 5-12/2

= -7/2

=-3.5
