    @Jdosio \[\Large \frac{a^4}{2a^2-4a^4} \times \frac{8a^3+1}{2a+4a^2}\]

    hint: factor \[\Large \frac{a^4}{2a^2-4a^4} \times \frac{8a^3+1}{2a+4a^2}\] \[\Large \frac{a^4}{2a^2(1-2a^2)} \times \frac{(2a+1)(4a^2-2a+1)}{2a(1+2a)}\]

    I used the sum of cubes formula to factor \(\Large 8a^3 + 1\)

    you can now cancel out the 2a + 1 on the right most fraction and the left one simplifies to a^2 ------ 2(1 - 2a^2)
