Answer 2

Hi...☺

Here is your answer...✌

LET $q(x) =2 {x}^{2} - 5x + 3$

It is given that,

p is zero of q(x)

Therefore,

q(p) = 0

$2 {p}^{2} - 5p + 3 = 0 \\ \\ 2 {p}^{2} - 2p - 3p + 3 = 0 \\ \\ 2p(p - 1) - 3(p - 1) = 0 \\ \\ (p - 1)(2p - 3) = 0 \\ \\ = > p - 1 = 0 \: \: or \: \: 2p - 3 = 0 \\ \\ = > p = 1 \: \: or \: \: p = \frac{3}{2 }$
HENCE,

Value of p is 1 or 3/2
