You can put this solution on YOUR website!
if the value of x is such that it make the denominator zero this expression would be undefined. so set 6x%5E2-9x%2B3=0
:
%283x-3%29%282x-1%29=0
:
3x-3=0 and 2x-1=0
:
3x=3 and 2x=1
:
x=1 and x=1/2......so x cannot be these values or expression would be undefined
