Question

ax + a2 + a - 2, then the number of integral
4
If the origin lies between zeroes of the polynomial f (x)
value(s) of a is​

Answer 1

Step-by-step explanation:

y=f(x)=

4

x

2

−ax+a

2

+a−2

For zeroes to be on either side of origin f(x)<0

a

2

+a−2<0

⇒(a+2)(a−1)<0⇒−2<a<1

⇒2 integers i.e,{−1,0}

Hence,(b) is correct answer.
