written as a multiple of the square root of five

So just subtract multiples of square to five it's just

like subtracting multiples of x And we get three times

square to five minus two times square to five which

is just the square root of five And so there

we have it Grow to forty five minus square twenty

is just the square root of five that's it We're 00:01:02.963 --> [endTime] done its egg
