Q. What is (f+g)(x)(f + g)(x)?\newlinef(x)=−3x2f(x) = -3x^2\newlineg(x)=x2+8xg(x) = x^2 + 8x\newlineWrite your answer as a polynomial or a rational function in simplest form.\newline______
  1. Combine like terms: Now we combine like terms to simplify the expression.\newline(f+g)(x)=−3x2+x2+8x(f + g)(x) = -3x^2 + x^2 + 8x\newline(f+g)(x)=(−3x2+x2)+8x(f + g)(x) = (-3x^2 + x^2) + 8x\newline(f+g)(x)=−2x2+8x(f + g)(x) = -2x^2 + 8x
