\n" );
document.write( "x^2 +3 - 15 =0 and x^2 + x+ 4=0. I' asking so that I'll understand what example to follow in my book , you don't have to work it out. I'm just tired of turnoing in my work with the wrong solutions and answers just because I have need to know what example to follow and where to look.
