I spent about 20 minutes on this one. This one is probably the hardest factoring problem I solved in my mathematical education. I am posting this one for you guys to solve. Factor (12xx^2)(12x+3x^2) + 4x^4. Show your work. Good luck! J.

(12xx^2)(12x+3x^2) + 4x^4 =(12x+xÂ²2xÂ²)(12x+xÂ²+2xÂ²)+4x^4 =[(x1)Â²2x^Â²][(x1)Â²+2xÂ²]+4x^4 =(x1)^4(2xÂ²)Â²+4x^4 =(x1)^4
