Question 913025
{{{x^2+3x<10}}}

{{{x^2+3x-10<0}}} ....write {{{3x}}} as {{{-2x+5x}}}

{{{x^2-2x+5x-10<0group

{{{(x^2-2x)+(5x-10)<0}}}...factor

{{{x(x-2)+5(x-2)<0}}}

{{{ (x-2)(x+5)<0}}}

solutions:


if {{{(x-2)<0}}} => {{{x<2}}}

if 
{{{(x+5)<0}}}=> {{{x<-5}}}

so, we use {{{-5<x<2}}}

{{{graph( 600, 600, -10, 10, -15, 15,x^2+3x-10)) }}}
