we simply have 4 function that we have to simply .
if
f(x1) = (x^2 + 8x + 12)
f(x2) = (x^2 + 4x - 12)
f(x3) = (x^2 + 6x + 8)
f(x4) = (x^2 + 3x - 10)
▪f(x1) = (x^2 + 8x + 12) = ( x+6)(x+2)
▪f(x2) = (x^2 + 4x - 12) = ( x+6)(x -2)
▪f(x3) = (x^2 + 6x + 8) = ( x+4)(x +2)
▪f(x4) = (x^2 + 3x - 10) = ( x+5)(x -2)
Now put them bacl to the main formula;
if f(x1) / f(x2) / f(x3) / f(x4) so
[( x+6)(x+2) / ( x+6)(x -2)] / [( x+4)(x +2) /( x+5)(x -2) ]
in the frst part we can remove ' x+6 '
so [ (x+2) / (x-2)] / [( x+4)(x +2) / ( x+5)(x -2) ]
so here far fraction * far fraction & near fraction * near fraction
it means if
f(x1) = (x+2)
f(x2) = (x-2)
f(x3) = ( x+4)(x +2)
f(x4) =( x+5)(x -2)
so we have ; [f(x1) * f(x4)] / [ f(x2) * f(x3) ]
[ (x+2) * ( x+5)(x -2) ] / [ (x-2) * ( x+4)(x +2) ]
wow now we can remove ' x-2 ' & ' x+2 '
so we have ; x+5 / x+4 = 1( x+4 ) +1
Its our answer.
very good question , good luck.

(x+5)/(x+4)
The thing you need to do here is simplify the equations. Factor each of them:
(x^2 + 8x + 12) = (x+6)(x+2)
(x^2 + 4x - 12 ) = (x+6)(x-2)
(x^2 + 6x + 8 ) = (x+4)(x+2)
(x^2 + 3x - 10 ) = (x+5)(x-2)
It works out pretty easy from there.
