It is proved that no matter what number m is, the value of square-m of algebraic formula m is always greater than that of algebraic formula m-2

It is proved that no matter what number m is, the value of square-m of algebraic formula m is always greater than that of algebraic formula m-2


It is proved that no matter what number m is, the value of square-m of algebraic formula m is always greater than that of algebraic formula m-2
m²-m-(m-2)
=m²-2m+2
=(m-1)²+1;
∵(m-1)²≥0;
(m-1) &# 178; + 1 ≥ 1 > 0 is tenable;
The value of the square-m of the algebraic formula m is always greater than that of the algebraic formula m-2 no matter what the number of M is
