Question

Plz solve and also tell me Why no infinity sign is involved here ​

Answer 1

Step-by-step explanation:

because we can get the exact answer

Answer 2

x cant be minus one as denominater will be zero.

then eqn will be un defined.

eqn should be greater than zero.

∴x must not be three .other wise eqn will be zero.

therefore roots are( -∞,-1)U(3,∞)

this is the answer.

Every value except -1 and 3 is exceptable and infity is also the answer.
