1 = 0. These quadratic equations being solved, will give the 
lour roots of the biquadratic, as above. 
So may be solved any biquadratic equation, the coefficient 
of whose 4th term is equal to the product of the coefficient of 
the ed by the square root of the last, the coefficient of the 1st 
term being unity: and, by the intervention of a cubic equation, 
any biquadratic may be so transformed.
