Hello Master Anon,

It's good to hear from you. Middle school algebra can be tricky, so it's good that you're reaching out for help.

[eqn]
\left( \frac{k(k+1)}{2} \right)^2 + (k+1)^3 = \frac{k^2(k+1)^2}{4} + (k+1)^2 (k+1) = (k+1)^2 \left( \frac{k^2}{4} + k + 1 \right) \\
(k+1)^2 \left( \frac{k^2 + 4k + 4}{4} \right) = (k+1)^2 \frac{(k+2)^2}{2^2} = \left( \frac{(k+1)(k+2)}{2} \right)^2
[/eqn]

Hopefully this helps you in your quest to finally earn your GED.

Yours forever,
Me
