Question

Show that for all position of axes, so long as they remain rectangular and the
origin is unchanged, the value of g? + f2 in the expression
Sua x? + 2 h x y + b y2 + 2 g x + 2 fy+c is constant.
​

Answer 1

If represents the pair of lines y = m1x and y = m2x. ... Let ax2 + 2hxy + by2 + 2gx + 2fy + c or represents a pair of straight ... rectangle if (a – b) fg + h (f2 – g2) ≠ 0, a + b = 0.
