Fraction 1: The quantity x squared plus 6 times x plus 9 over the quantity x minus 1.
Fraction 2: the quantity x squared minus 9 over the quantity x squared minus 2 times x plus 1.

 Find Fraction 1 over Fraction 2.

Correct answer:

d = fr((x^2+6)(x+9), x-1) * fr(x^2-2x+1, x^2-9)

Step-by-step explanation:

f1 =  x1(x2+6)(x+9) f2 =  x22x+1(x29)  d = f2f1 d =  x1(x2+6)(x+9)    x29x22x+1 d=x1(x2+6)(x+9) x29x22x+1
