Question

What is the factored form of the expression?

k^2 – 9h^2
A. (k + 3h)(k + 3h)
B. h^2(k + 3)(k – 3)
C. (k + 3h)(k – 3h)
D. (k – 3h^2)(k + 3)

Answer 1

More like a difference of squares.


\(\Large \color{MidnightBlue}{\Rightarrow k^2 - 9h^2 \Longrightarrow k^2 - (3h)^2 }\)
\(\Large \color{MidnightBlue}{\Rightarrow (k + 3h)(k - 3h) }\)
