184.5²+184.5×31+15.5²用因式分解计算
184.5²+184.5×31+15.5²用因式分解计算
184.5²+184.5×31+15.5²用因式分解计算
184.5²+184.5×31+15.5²
=184.5²+2×184.5×15.5+15.5²
=(184.5+15.5)²
=200²
=40000
184.5²+184.5×31+15.5²
=(184.5+15.5)^2
=200^2
=40000
184.5²+184.5×31+15.5²
=184.5²+2×184.5×15.5+15.5²
=(184.5+15.5)²
=200²
=40000
184.5²+184.5×31+15.5²
=(184.5+15.5)²
=200²
=40000
原式=184.5*184.5+184.5*2*15.5+15.5*15.5
=（184.5+15.5）^2
=200^2
=40000
(184.5+15.5)^2=40000
