Question

Find the values of x for which the denominator is equal to zero for 2x^2+5/x^2-2x .

Answer 1

Let's see

$\\ \rm\rightarrowtail x^2-2x=0$

$\\ \rm\rightarrowtail x(x-2)=0$

$\\ \rm\rightarrowtail x=0\:or\:x-2=0$

$\\ \rm\rightarrowtail x=0\:or\:x=2$

Answer 2

$\green{••••••••••••••••••••••} \blue{••••••••••••••••••••••••••}$

$\sf {x^2 - 2x = 0}$

$\sf {x ( x - 2) = 0}$

$\sf {x = 0 \: or \: x-2 = 0}$

$\sf \green{ {x = 0 \: or \: x = 2}}$
