Q. What is (f+g)(x)(f + g)(x)?\newlinef(x)=−x2−10xf(x) = -x^2 - 10x\newlineg(x)=−3xg(x) = -3x\newlineWrite your answer as a polynomial or a rational function in simplest form.\newline______
  1. Identify Formula: Identify the formula for (f+g)(x)(f + g)(x). The correct formula is (f+g)(x)=f(x)+g(x)(f + g)(x) = f(x) + g(x).
  2. Substitute Values: We have f(x)=−x2−10xf(x) = -x^2 - 10x and g(x)=−3xg(x) = -3x. Substitute these values into the formula to get (f+g)(x)=(−x2−10x)+(−3x)(f + g)(x) = (-x^2 - 10x) + (-3x).
  3. Simplify Equation: Simplify the equation (f+g)(x)=(−x2−10x)+(−3x)(f + g)(x) = (-x^2 - 10x) + (-3x) to find (f+g)(x)(f + g)(x).
    (f+g)(x)=−x2−10x−3x(f + g)(x) = -x^2 - 10x - 3x
    (f+g)(x)=−x2−13x(f + g)(x) = -x^2 - 13x
