First, try to factor both expressions:
x2 - 4x - 5
= (x - 5)(x + 1)
x2 - 3x - 10
= (x - 5)(x + 2)
So both expressions have (x - 5) as a factor, which means you only need to include that once between the two of them. The least common multiple then would be:
(x - 5)(x + 1)(x - 2)
If you need to expand that out, it becomes:
(x - 5)(x2 - x - 2)
= x3 - x2 - 2x - 5x2 + 5x + 10
= x3 - 6x2 + 3x + 10
