Q. What is (f+g)(x)?f(x)=2x+5g(x)=−3x2Write your answer as a polynomial or a rational function in simplest form.______
Combine like terms: Now we combine like terms. Since there are no like terms to combine (the terms are of different degrees), we just write the expression in standard polynomial form, which is usually from highest degree to lowest degree.(f+g)(x)=−3x2+2x+5
