The first number in the top row multiplies with the top number in the second matrix and that gets added to the second number in the top row multiplied by the bottom number in the second matrix.

Then the bottom row in the first matrix, multiplies the same way:

6 x -5 + -1 x 4 = -34

-4 x -5 + 3 x 4 = 32

The answer would be E.
