Vicky factored 30x2 + 76x + 48 as follows:

Line 1 30x2 + 76x + 48
Line 2 30x2 + 36x + 40x + 48
Line 3 6x(5x + 6) + 8(5x +6)
Line 4 (6x + 8)(5x + 6)
A: Did Vicky completely factor the polynomial? Justify your response by explaining why it is is factored completely or by showing the correct solution if it is not factored completely.
B: Would the problem produce a different result if Line 2 was written as 30x2 + 40x + 36x + 48? Explain why or why not.
