Free webinar on Robotics (Block Chain) Learn to create a Robotic Device Using Arduino
30th Jan @ 5:00PM for Grade 1 to 10
Roots of equation x.x -10cx-11d=0 are a and b and those of x.x -10ax-11b=0 are c and d. Then a+b+c+d=? Roots of equation x.x -10cx-11d=0 are a and b and those of x.x -10ax-11b=0 are c and d. Then a+b+c+d=?
From first eqn.a+b that is sum of roots => 10cFrom second eqn.c+d = >10aTherfore,a+b+c+d = 10(a+c)
