You can put this solution on YOUR website!
equation is:
\n" ); document.write( "2x^2 - 3x - 2 <= 0
\n" ); document.write( "set it equal to 0 and you get:
\n" ); document.write( "2x^2 - 3x - 2 = 0
\n" ); document.write( "factor it and you get:
\n" ); document.write( "x = -.5 and or x = 2
\n" ); document.write( "graph it on the number line and you see that the function is greater than 0 when x is smaller than -.5 and it is less then 0 when x is between -.5 and 2 and it is greater than 0 when x is greater than 2.
\n" ); document.write( "bottom line:
\n" ); document.write( "you are correct and the book is wrong.
\n" ); document.write( "it happens more times than you think.
\n" ); document.write( "the books are not perfect.
\n" ); document.write( "here's a graph of your equation.
\n" ); document.write( "\"graph%28600%2C600%2C-3%2C3%2C-5%2C5%2C2x%5E2+-+3x+-+2%29\"
