Question 723757
{{{(2x-5)(9x-15)=0}}}...here you have completely factored quadratic equation (graph is a parabola); so, you will have two roots


if {{{2x-5=0}}}....=>...{{{2x=5}}}....=>...{{{x=5/2}}}...=>...{{{x=2.5}}}

and

if {{{9x-15=0}}}....=>...{{{cross(9)3x=cross(15)5}}}....=>...{{{3x=5}}}...=>...{{{x=5/3}}}...=>...{{{x=1.7}}}


{{{ graph( 600, 600, -5, 5, -5, 10,(2x-5)(9x-15)) }}}
