If the three lines y=m1x+c1,y=m2x+c2 and y=m3x+c3 are concurrent then

1.	If the three lines y=m1x+c1,y=m2x+c2 and y=m3x+c3 are concurrent then show that, m1(c2−c3)+m2(c3−c1)+m3(c1−c2)=0
Answer» If the three lines $y = m_{1} x + c_{1}, y = m_{2} x + c_{2}$ and $y = m_{3} x + c_{3}$ are concurrent then show that, $m_{1} (c_{2} - c_{3}) + m_{2} (c_{3} - c_{1}) + m_{3} (c_{1} - c_{2}) = 0$

If the three lines y=m1x+c1,y=m2x+c2 and y=m3x+c3 are concurrent then show that, m1(c2−c3)+m2(c3−c1)+m3(c1−c2)=0

Answer»

If the three lines $y = m_{1} x + c_{1}, y = m_{2} x + c_{2}$ and $y = m_{3} x + c_{3}$ are concurrent then show that,

$m_{1} (c_{2} - c_{3}) + m_{2} (c_{3} - c_{1}) + m_{3} (c_{1} - c_{2}) = 0$
