Question

if pq are the zeroes of polynomial if (x) 2x^2 -7x +3 .find the value of p^2 +q^2

Answer 1

here is your answer by SmArTY SUjeET yaduvanshi,

Given that quardratic equation,
2x²-7x+3
Sum of zeroes=-b/a=-(-7)/2
product of zeroes=c/a=3/2

then,
P²+q²
=}(p+q)²-2pq
=}(7/2)²-2(3/2)
=}49/4-3/1
=}49-12/4
=}37/4

that's all


any problem ask Sujeet
