Divide both sides by the lead coefficient. For your problem, the lead coefficient is 1, so there is nothing to do.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 2:. Add the opposite of the constant term on the left to both sides, i.e., combine the constant terms and put them on the right hand side:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 3:. Divide the coefficient on the 1st degree term by 2 and square the result, adding that value to both sides of the equation.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 4:.
