A student solved a rational equation using the steps shown below.

x 3
------ - ------ = -9, x ? -1, 2 (This worded is x over x + 1 subtract 3 over x - 2 equals -9)
x + 1 x - 2

Step 1: x (x - 2) - 3 (x + 1) = -9

Step 2: x² - 2x - 3x - 3 = -9

Step 3: x² - 5x + 6 = 0

Step 4: (x - 3) (x - 2) = 0

Step 5: x = 3, 2

There were two errors made in the above solution. The errors occurred in Steps

A. 1 and 3
B. 1 and 5
C. 2 and 4
D. 2 and 5
