Algebra.Com's Answer #23164 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Okay...we need to combine these fractions and then simplify...notice how the denominator in the second fraction is the first denominator squared... \n" ); document.write( "(3x/x-1) - (x-4/x^2-2x+1) = \n" ); document.write( "(3x/x-1) - (x-4/(x - 1)^2) \n" ); document.write( "Thus we will need to multiply the first fraction by (x - 1) / (x - 1)... \n" ); document.write( "(3x(x - 1)/(x - 1)^2) - (x-4/(x - 1)^2) and put it all over the same denominator: \n" ); document.write( "[(3x(x - 1) - (x - 4)] / (x - 1)^2 \n" ); document.write( "Now expand the numerator and simplify... \n" ); document.write( "[(3x(x - 1) - (x - 4)] / (x - 1)^2 = \n" ); document.write( "(3x^2 - 3x - x + 4) / (x - 1)^2 = \n" ); document.write( "(3x^2 - 4x + 4) / (x - 1)^2 \n" ); document.write( "Nothing more can be done with this one...that's the answer. \n" ); document.write( " |
