Answer 2

Other root would be 2/3

Step-by-step explanation:

Given equation,

$3x^2-5x+2$

Since, if m and n are roots of $ax^2+bx+c$ then,

$m+n=-\frac{b}{a}$

Consider x and y are roots of $3x^2-5x+2$,

Then,

$x+y=\frac{5}{3}$

If x = 1,

$1+y=\frac{5}{3}$

$\implies y =\frac{5}{3}-1=\frac{5-3}{3}=\frac{2}{3}$

Hence, other root is 2/3.
