✰✰ ANSWER ✰✰

$⇢{x}^{2}-3x+2=0$

$⇢Putting\:x=2$

$⇢{(2)}^{2}-3(2)+2=0$

$⇢4-6+2=0$

$⇢-2+2=0$

$⇢0=0$

Yes x=2 is the solution of x²– 3x + 2 = 0.

_______________________

$⇢{x}^{2}-3x+2=0$

$⇢Putting\:x=-1$

$⇢{(-1)}^{2}-3(-1)+2=0$

$⇢1+3+2=0$

$⇢6≠0$

No, x=-1 is not a solution of x²– 3x + 2 = 0.
