Answer:
The factored form is(k+3h)(k-3h)
Step-by-step explanation:
The given expression is [tex]k^2-9h^2[/tex]
Write this expression in difference of squares form
[tex](k)^2-(3h)^2[/tex]
Use the difference of squares formula: [tex]a^2-b^2=(a+b)(a-b)[/tex]
Here,
a = k
b = 3h
Thus, we have
[tex](k)^2-(3h)^2=(k+3h)(k-3h)[/tex]
Therefore, the factored form is(k+3h)(k-3h)
