You can put this solution on YOUR website!
solve (x-2)^2(2x+1) <= 0
\n" ); document.write( "----------
\n" ); document.write( "1st: Solve the EQUALITY:
\n" ); document.write( "x = 2 or x = -1/2
\n" ); document.write( "-------------------------------
\n" ); document.write( "Draw a number line and plot the two values, x = -1/2 and x = 2
\n" ); document.write( "--------------------------------
\n" ); document.write( "Now, pick a test value from each of the three line intervals to
\n" ); document.write( "see where the solutions for the inequality are.
\n" ); document.write( "--------------------------------
\n" ); document.write( "Test is (x-2)^2(2x+1) < 0
\n" ); document.write( "Testing x=-1 you get [(-3)^2](-1) < 0; true so solutions in (-inf,-1/2)
\n" ); document.write( "Testing x = 1 you get [(-1)^2(3)] < 0 ; false so no solutions in (-1/2,2)
\n" ); document.write( "Testing x = 3 you get [(1)^2*7] < 0 ; false so no solutions in (2,+inf)
\n" ); document.write( "-----------------------------------
\n" ); document.write( "Final Answer {x | -inf < x < -1/2)}
