Note that 5p^2 + 16p - 16 = (p+4)(5p-4), which helps somewhat. Make it a habit to try and factorize quadratics when given this kind of problem to aid in finding easy common denominators.
In this problem, we could make the common denominator of each term (4-5p)(5p-4)(p+4).
For example, this would mean that in the first term the numerator would be 8(5p-4)(p+4).
Do the same for the other two terms.
Combine the terms.
Simplify the numerator.
Divide by monomials ex. (4-5p),(5p-4),(p+4) if possible.
