You can put this solution on YOUR website!
x^3 - 9x = 0 Factorise x out
\n" ); document.write( "x (x^2 - 9) = 0
\n" ); document.write( "x = 0, x^2 - 9 = 0
\n" ); document.write( "Solving x^2 - 9 = 0 ( This is a difference of two square
\n" ); document.write( "(x + 3) ( x - 3)= 0
\n" ); document.write( "Equate each of them to zero
\n" ); document.write( "x = -3, and x = 3
\n" ); document.write( "Hence, x=0, x = 3, and x = -3 \n" ); document.write( "
