((x+1)/(x^2-25))/((x+5)/(x^2+8x+7))
((x+1)/(x^2-25)) * (x^2+8x+7)/(x+5)
(x^3+9x^2+15x+7)/(x^3+5x^2-25x-125)
((x+1)/(x^2-25)) * (x^2+8x+7)/(x+5)
(x^3+9x^2+15x+7)/(x^3+5x^2-25x-125)

since you said "product" maybe you meant
((x+1)/(x^2-25)) * ((x+5)/(x^2+8x+7))
(x+1)/((x-5)(x+5)) * (x+5)/((x+1)(x+7))
1/((x-5)(x+7))
1/(x^2+2x-35)
((x+1)/(x^2-25)) * ((x+5)/(x^2+8x+7))
(x+1)/((x-5)(x+5)) * (x+5)/((x+1)(x+7))
1/((x-5)(x+7))
1/(x^2+2x-35)
