Question 57666
simplify:
{{{5x^2+15x/x^3+27}}}  Reduce the middle term.
{{{5x^2+15/x^2+27}}}  The LCD is {{{x^2}}}, whatever you do to the denominator to get that also do to the numerator.
{{{5x^2*(x^2/x^2)+15/x^2+27(x^2/x^2)}}}
{{{5x^4/x^2+15/x^2+27x^2/x^2}}}  Now that they all have the same denominator you can combine their numerators.
{{{(5x^4+15+27x^2)/x^2}}}  It's customery to write polynomials in decending order.
{{{(5x^4+27x^2+15)/x^2}}}  All done!!!:-)
Happy Calculating!!!
