simplify:
5x%5E2%2B15x%2Fx%5E3%2B27 Reduce the middle term.
5x%5E2%2B15%2Fx%5E2%2B27 The LCD is x%5E2, whatever you do to the denominator to get that also do to the numerator.
5x%5E2%2A%28x%5E2%2Fx%5E2%29%2B15%2Fx%5E2%2B27%28x%5E2%2Fx%5E2%29
5x%5E4%2Fx%5E2%2B15%2Fx%5E2%2B27x%5E2%2Fx%5E2 Now that they all have the same denominator you can combine their numerators.
%285x%5E4%2B15%2B27x%5E2%29%2Fx%5E2 It's customery to write polynomials in decending order.
%285x%5E4%2B27x%5E2%2B15%29%2Fx%5E2 All done!!!:-)
Happy Calculating!!!
