    First, factorise the two expressions. Can you do that?

    I need to know whether you want to check your answer or whether you want to know how to do the sum.

    highest power of the factor x is 1(in both) highest power of the factor (x + 5) is also 1(in the first one) highest power of the factor (x - 5) is also 1(in the second one) So the LCM would be: \[x(x + 5)(x - 50)\]
