Question

What is the factored form of the expression? k2 – 9h2

Answer 1

Answer:

The factored form is(k+3h)(k-3h)

Step-by-step explanation:

The given expression is $k^2-9h^2$

Write this expression in difference of squares form

$(k)^2-(3h)^2$

Use the difference of squares formula: $a^2-b^2=(a+b)(a-b)$

Here,

a = k

b = 3h

Thus, we have

$(k)^2-(3h)^2=(k+3h)(k-3h)$

Therefore, the factored form is(k+3h)(k-3h)

Answer 2

The factored form of this expression would be :

(k-3h)(k+3h).
