-17\n" ); document.write( "x>10\r
\n" ); document.write( "\n" ); document.write( "The roots are x=-17,10,and -4
\n" ); document.write( "What you have to find is when y>0
\n" ); document.write( "There are three sections to consider.
\n" ); document.write( "a)from x=-17 to x=-4
\n" ); document.write( "b)from x=-4 to 10
\n" ); document.write( "c)and x>10
\n" ); document.write( "As it turns out b) 10>x>-4 is <0 and a and c are >0
\n" ); document.write( "How do you find out? Plug a value in for x in those three intervals and find y.
\n" ); document.write( "(x+17)(x-10)(x+4)>0
\n" ); document.write( "b)Try x=5 since I said it doesn't work
\n" ); document.write( "22*-5*9 you can see that is negative
\n" ); document.write( "a) Try -5
\n" ); document.write( "17-5*-5-10*4-5
\n" ); document.write( "12*-15*-1 >0
\n" ); document.write( "c)Try 20
\n" ); document.write( "37*10*24>0 yes
\n" ); document.write( "
\n" ); document.write( "
