The correct answer choice is: x not equal -2, 1
from the original equation,
(6-x)/(x^2 + 2x - 3) + (x^2 - 4x - 12)/(x^2 + 4x + 3)
= (6-x)/((x+3)(x-1)) + ((x-6)(x+2))/((x+3)(x+1)
x ≠ -3,-1,1
simplified, we get
(x-6)(x^2-3) / (x+3)(x^2-1)
so no new restrictions, In fact, x=6 or -2 is a solution
(6-x)/(x^2 + 2x - 3) + (x^2 - 4x - 12)/(x^2 + 4x + 3)
= (6-x)/((x+3)(x-1)) + ((x-6)(x+2))/((x+3)(x+1)
x ≠ -3,-1,1
simplified, we get
(x-6)(x^2-3) / (x+3)(x^2-1)
so no new restrictions, In fact, x=6 or -2 is a solution
The correct answer is that there are no new restrictions on x, and in fact, x = 6 or -2 is a solution.
