If m = 0, then prove that a^12 - 18a^6 + 1= 0, when m = a^2 - √5a + 1

hi, i am not sure about this one but i think its d,

hope this !

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
