    then you have \[\frac{y^7}{y^5}\] since they have the same base you can use the above property so \[\frac{y^7}{y^5}=y^{7-5}\]

    so combine your constant and your variables to get \[2y^{7-5}=2y^2\]

    so \[\frac{18x^5+6x^4-12x^3}{6x^2}=\frac{18x^5}{6x^2}+\frac{6x^4}{6x^2}-\frac{12x^3}{6x^2}\]
