Answer

$3y^{5a}-3y^{3a}-3.2y$

Work Step by Step

We are given $(9y^{5a}-4y^{3a}+1.5y)-(6y^{5a}-y^{3a}+4.7y)$. We can subtract the second polynomial from the first polynomial by adding the opposite of the second polynomial to the first polynomial. $(9y^{5a}-4y^{3a}+1.5y)+(-6y^{5a}+y^{3a}-4.7y)$ Next, we can combine like terms. $(9y^{5a}-6y^{5a})+(-4y^{3a}+y^{3a})+(1.5y-4.7y)=3y^{5a}-3y^{3a}-3.2y$
