Find R(x)=f(x)/g(x), where f(x) and g(x) are given
f(x)=2a^2+7a+5/5a+25
g(x)=a^2-2a-3/a^2+2a-15

Find R(x) with ÷
So far so good. Have you tried factoring each expression, to eliminate common factors? These all appear to factor easily.
Find R(x)= f(x)÷g(x)
F(x)=(2a^2+7a+5)/(5a+25)
G(x)= (a^2-2a-3)/(a^2+2a-15)
2(a+5)(a+1)/5(a+5)*(a+5)(a-3)/(a-3)(a+1)
=2(a+5)/5.
F(x)=(2a^2+7a+5)/(5a+25)
G(x)= (a^2-2a-3)/(a^2+2a-15)
2(a+5)(a+1)/5(a+5)*(a+5)(a-3)/(a-3)(a+1)
=2(a+5)/5.
looks good to me.
