Q. What is (fg)(x)(f - g)(x)?\newlinef(x)=4xf(x) = 4x\newlineg(x)=3x23g(x) = 3x^2 - 3\newlineWrite your answer as a polynomial or a rational function in simplest form.
  1. Identify Formula: Identify the formula for (fg)(x)(f - g)(x). The correct formula is (fg)(x)=f(x)g(x)(f - g)(x) = f(x) - g(x).
  2. Substitute Values: We have f(x)=4xf(x) = 4x and g(x)=3x23g(x) = 3x^2 - 3. Substitute these values into the formula to get (fg)(x)=4x(3x23)(f - g)(x) = 4x - (3x^2 - 3).
  3. Simplify Equation: Simplify the equation (fg)(x)=4x(3x23)(f - g)(x) = 4x - (3x^2 - 3) to find (fg)(x)(f - g)(x).(fg)(x)=4x3x2+3(f - g)(x) = 4x - 3x^2 + 3 (Note that we distribute the negative sign across the terms in the parentheses).
  4. Rearrange Terms: Rearrange the terms in descending order of the power of xx to write the polynomial in standard form.(fg)(x)=3x2+4x+3(f - g)(x) = -3x^2 + 4x + 3
