    need a common denominator 5d - 10 factors into 5(d - 2) 10d - 20 factors into 10(d - 2) 10(d - 2) can be written as 2 * 5 * (d - 2) So... common denominator is 2 * 5 * (d - 2) or 10(d - 2) = 10d - 20 So to make 5d - 10 into 10d - 20, you would multiply by 2 so take the top and bottom times 2 on the first fraction. 8d 9d -------- + -------- 10d - 20 10d - 20 17d ------- 10d - 20
