Answer:
8(√5x - √6)(√5x + √6).
Explanation:
First, we can factor out the greatest common factor, which is 8:
8(5x^2 - 6)
Next, we can use the difference of squares formula to factor further:
8(√5x - √6)(√5x + √6)
Therefore, the expression 40x^2 - 48 can be factored completely as 8(√5x - √6)(√5x + √6).
