Okay so notice that the bottom of the second fraction is infact the "difference of two squares" i.e. (a^2-64)=(x-8)(x+8), then multiply the first fraction by x-8 so that you have equal denominators then you may add them together simply and simplify if nessecary

Lcm of a+8 and a^2-64 is a^2-64 a^2-64=(a-8)(a+8) So the common denominator is a^2-64 With vat expression do u need to multiply (a+8) to make it a^2-64?
