Algebra.Com's Answer #258316 by stanbon(75887) ![]() You can put this solution on YOUR website! 6x^2-5x-1/12x^2-11x+2 is less than 0 \n" ); document.write( "------ \n" ); document.write( "Factor: \n" ); document.write( "[(6x+1)(x-1)]/[(3x-2)(4x-1)] < 0 \n" ); document.write( "------ \n" ); document.write( "Find the boundary values for the inequality \n" ); document.write( "which are the solutions to the EQUALITY. \n" ); document.write( "Those values are x = -1/6 and x = 1 \n" ); document.write( "Also take note of indeterminate values. \n" ); document.write( "Those are x = 2/3 and x = 1/4 \n" ); document.write( "------ \n" ); document.write( "Draw a number line and plot the boundary values: \n" ); document.write( "....-1/6....1/4....2/3....1.... \n" ); document.write( "--- \n" ); document.write( "To find the solutions for the inequality, test \n" ); document.write( "a value from each of the three bounded intervals \n" ); document.write( "in the inequality. \n" ); document.write( "[(6x+1)(x-1)]/[(3x-2)(4x-1)] < 0\r \n" ); document.write( "\n" ); document.write( "--- \n" ); document.write( "If x = -1 you get: (-*-)/(-*-) < 0; this is false \n" ); document.write( "----- \n" ); document.write( "If x = 0 you get: (+*-)/(-*-) < 0: true, so solutions in (-1/6,1/4) \n" ); document.write( "----- \n" ); document.write( "Do the same for x = 1/3 , for x = 5/6, and x = 1 \n" ); document.write( "===================================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
