Answer
5(4h+5)(4h-5)
Work Step by Step
80h$^2$-125
5(16h$^2$-25)
Inside of the parentheses is a difference of squares expression. If the square root of the first term is a and the square root of the second term is b, the factorization is (a+b)(a-b).
$\sqrt {16h^2}$=4h and
$\sqrt {25}$=5. So the factorization is
5(4h+5)(4h-5).
