By writing -810 as -729-81, I could factor the equation by grouping, which is the distributive property in reverse.
M^3+M^2=810 M=9 M=-5±Sqrt[65]i
Genius man ♥️♥️
m^2(m+1) = 9^2*(9+1) => m=9
You are a genius and so sweet my friend ♥️♥️
by fakt. , (m-9)(m^2+10m+90)=0 , m=9 , m^2+10m+90=0 , m=-5 +/- i*V65 ,
You are a so sweet my friend ♥️♥️
