What is the simplified form of x+1 over x2+x-6 divided x2+5x+4 over x+3

. . (x + 1) . . . . . . (x² + 5x + 4)
÷ =
(x² + x − 6) . . . . . (x − 2)

. . (x + 1) . . . . . . . (x + 4)(x + 1)
÷ =
(x + 3) (x − 2) . . . . . (x − 2)

. . (x + 1) . . . . . . . . . (x − 2)
* =
(x + 3) (x − 2) . . . (x + 4)(x + 1)

. . 1 . . . . . . 1
* =
(x + 3) . (x + 4)

. . . . . 1
=
(x + 3) (x + 4)

. . . . 1

x² + 7x + 12
