If f(a)=a^2, what is the value of (f(a+b)+f(a))/b ? Select the correct option:  A) a  B) b  C) 2a  D) 2a + b  E) 2a+b+2a^2
start with f(a+b) before start calculations: f(a+b)=(a+b)^2= a^2+2ab+b^2   a^2+2ab+b^2 + a^2/b = (simplify a^2)   2ab+b^2/b+2a^2 = (cancel b's)   = 2a+b+2a^2   Answer : 2a+b+2a^2
