Answer 2

Answer:

$\text{The value of }\frac{1}{p}-\frac{1}{q} \text{ is }\frac{1}{2}$

Step-by-step explanation:

Given p and q are the roots of the equation

$x^2-3x+2=0$

we have to find the value of $\frac{1}{p}-\frac{1}{q}$

$x^2-3x+2=0$

$=x^2-x-2x+2=0\\\\=x(x-1)-2(x-1)=0\\\\=(x-1)(x-2)=0\\\\x=1, x=2$

Hence, roots of given equation are 1 and 2 i.e

p=1 and q=2

$\frac{1}{p}-\frac{1}{q}$

$=\frac{1}{1}-\frac{1}{2}$

$=1-\frac{1}{2}=\frac{1}{2}$

$\text{The value of }\frac{1}{p}-\frac{1}{q} \text{ is }\frac{1}{2}$
