Solution

The correct option is A 1
The total number of solution of
2x+3x+4x5x=0 is (are)
Let f(x)=5x
and g(x)=2x+3x+4x
f(x)=50=1
g(0)=20+30+40
=3
As f(x) and g(x) are experiential they are
movement
At x=0
f(x) is below g(x)
At x=3
f(3)=53=125
g(x)=23+33+43
=8+27+64
=99
Thus f(x) is above g(x)
Thus there exist a solution is xϵ(0,3)
