Question

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

Answer 1

Given $x^2-3x+2=0$
$x^2-2x-1x+2=0$ (Resolving the expression)
$x(x-2)-1(x-2)=0$ (Taking common factors)
$(x-2)(x-1)=0$ (Taking common factors)
$\therefore x-2=0$ or $x-1=0$ (Equating each factor to zero)
$\therefore x=2$ or $x=1$
$\therefore 2$ and $1$ are the roots of $x^2-3x+2=0$
