You can put this solution on YOUR website!
\"y=4x%5E2%2B8x-5\"\r
\n" ); document.write( "\n" ); document.write( "The x-intercepts are the values of x where y = 0 so we need to solve the following for x:\r
\n" ); document.write( "\n" ); document.write( "4x^2 + 8x - 5 = 0\r
\n" ); document.write( "\n" ); document.write( "(2x + 5)*(2x - 1) = 0\r
\n" ); document.write( "\n" ); document.write( "So the solutions are where 2x + 5 = 0 and 2x - 1 = 0.\r
\n" ); document.write( "\n" ); document.write( "Solve these two equations for x.
