1) Two distinct real roots: {eq}r_1, r_2 {/eq}. 2) One repeated real root: {eq}r_1 {/eq}. 3) Two complex roots which are complex conjugates: {eq}\alpha \pm \beta i {/eq}. The general sol...
Two sequences (HiBtCoV/3740-2 and RaBtCoV/4991) were homologous to betacoronaviruses, all other 150 sequences were homologous to alphacoronaviruses” OK, so this RaTG13 virus in the WIV seems to have originally been this RaBtCoV/4991 variant that came from the Yunnan Province of China. ...
