If (mx)=x+5/x-1 and n(x),= x-3, which function has the same domain as (m°n)(x)

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

then
