Question

if P, Q are zeros of polynomial f x equals to 2 x square - 7 x + 3 find the value of p square + Q square

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Step-by-step explanation:

We know that,

Sum of zeroes = -b/a

= -(-7)/2

=7/2

product of zeros = c/a

=3/2

(p+q)^2=p^2+q^2+2pq

p^2+q^2=(p+q)^2-2pq

p^2+q^2=(7/2)^2-2×3/2

p^2+q^2=14/4-3

p^2+q^2=7/2-3

p^2+q^2=7-6/2

p^2+q^2=1/2 Ans
