Full solution

Q. Find the product. Simplify your answer. \newlinef2(f2+4)f^2(-f^2 + 4)
  1. Distribute f2f^2: f2(f2+4)f^2(-f^2 + 4)\newlineDistribute f2f^2 to both f2-f^2 and +4+4.\newlinef2(f2+4)=f2(f2)+f2(4)f^2(-f^2 + 4) = f^2(-f^2) + f^2(4)
  2. Simplify f2(f2)f^2(-f^2): Simplify f2(f2)f^2(-f^2).
    f2(f2)f^2(-f^2)
    =f2f2= f^2 \cdot -f^2
    =f2+2= -f^{2+2}
    =f4= -f^4
  3. Simplify f2(4)f^2(4): Simplify f2(4)f^2(4).
    f2(4)f^2(4)
    = 4×f24 \times f^2
    = 4f24f^2
  4. Combine results: Combine the results from Step 22 and Step 33.\newlineWe found:\newlinef2(f2)=f4f^2(-f^2) = -f^4\newlinef2(4)=4f2f^2(4) = 4f^2\newlineSo, f2(f2+4)=f4+4f2f^2(-f^2 + 4) = -f^4 + 4f^2
