Question

8.954的3立方-7.954 的3立方-26.54的2平方+37.46的2平方 分解因式

Answer 1

8.954的3立方-7.954 的3立方-26.54的2平方+37.46的2平方
=(8.954-7.954)(8.954^2+8.954*7.954+7.954^2)+(37.46-26.54)(37.46+26.54)
=8.954^2+8.954*7.954+7.954^2+10.92*64
=(8.954-7.954)^2+8.954*7.954*3+10.92*64
=1+(9-0.046)(8-0.046)*3+10.92*64
=1+216-51*(0.046)+3*0.046^2+10.92*64
=857-51*0.046+3*0.046^2+0.92*64
=857-51*0.046+3*0.046^2+0.046*1280
=857+1229*0.046+3*0.046^2
=913.540348
