If a, b, c are positive real numbers, then the number of real roots of equation ax 2 + b |x| + c = 0 is -
Text Solution
Verified by ExpertsThe correct answer is:
A
ax 2 + bx + c=0, (x ≥ 0) or ax 2 – bx + c = 0, (x < 0)
Here a, b, c > 0 Here a ′ >0, b ′ < 0, c ′ >0
so, both roots are –ve so, both roots are +ve
but x ≥ 0 so, no sol n . but x < 0 so, no sol n .
so, Number of solutions are 0.
