The square of 2 (Y-X) - 7 (X-Y) + 6 (X-Y) - 3 (Y-X)
2(y-x)²-7(x-y)+6(x-y)-3(y-x)²
=-(y-x)²-(x-y)
=-(x-y)²-(x-y)
=-(x-y)[(x-y)+1]
=(y-x)(x-y+1)

- 10. The laser rangefinder emits a laser pulse beam at the target The laser rangefinder emits a laser pulse beam to the target, receives the reflected laser beam, and measures the time taken for the laser column to go back and forth. Then the distance between the measured celestial body and the earth can be calculated. The distance between the earth and the moon is the eighth power of 3.8 * 10, Now the distance between the earth and the moon can be measured by laser rangefinder with an accuracy of plus or minus 10cm. Laser ranging technology is widely used in man-made earth satellite monitoring, geodesy and other aspects Known: Ask for: I will. Come on in~
