1. x^4 < x^2
\n" ); document.write( "Divide both sides by x^2, results
\n" ); document.write( "x^2 < 1
\n" ); document.write( ":
\n" ); document.write( "2. \"2%2F%28x%2B8%29+%3E+3%2F%28x-9%29\"
\n" ); document.write( "Cross multiply
\n" ); document.write( "2(x-9) > 3(x-9)
\n" ); document.write( "2x - 18 > 3x - 27
\n" ); document.write( "3x - 3x > - 27 + 18
\n" ); document.write( "-x > - 9
\n" ); document.write( "x has to be positive, mult both sides by -1, this reverses the inequality sign
\n" ); document.write( "x < 9
\n" ); document.write( ":
\n" ); document.write( "3. x^3 - 5x^2 - 5x + 25 > 0
\n" ); document.write( "graph this
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-5%2C+10%2C+-20%2C+30%2C+x%5E3+-+5x%5E2+-+5x+%2B+25%29+\"
\n" ); document.write( "you can see x > 0 -2.2 to +2.2; when x > 5
\n" ); document.write( "
