讨论一类直线方程的几何意义

The Geometric Singniticance Of The Straight Line Equation

论述直线方程Ax0 x +B2 (y0 x +x0 y) +Cy0 y +D2 (x +x0 ) +E2 (y0 +y) +F =0与二次曲线Ax2 +Bxy+Cy2+Dx+Ey+F =0的关系 ,讨论了直线方程Ax0 x +B2 (y0 x +x0 y) +Cy0 y +D2 (x +x0 ) +E2 (y0 +y)

The paper discusses the relation between striaght line Ax 0x+B2(y 0x+x 0y)+Cy 0y+D2(x+x 0)+E2(y 0+y)+F=0 and quadratic curve Ax 2+Bxy+Cy 2+Dx+Ey+F=0.Discusses the geometric significance of the straight line equatiom Ax 0x+B2(y 0x+x 0y)+Cy 0y+D2(x+x 0)+E2(y 0+y)+F=0.
