Excellent observation on the first method. 😊
Power 6 can be broken into 3 .. with a^2-b^2.... Wiout...
Thank you
X^2+10x +25 and x^2+6x+9 and then 64 is 4^3 so you bring it inside and you obtain 4x+16 and then substitution is clear. When you subtract the first two expressions within the cube you get the 3rd expression within the cube.
