Follow explanation. Your solution: $k=+-3.2$

Your equation can be arranged

$k^2 = 10.24$

$sqrt(k^2) = +-sqrt (10.24)$

$k=+-3.2$

Because of the fact that $sqrt(k^2) = +-(k^2)^0.5 = +-k$

There are two possible roots.

$k=+-3.2$

Square root both sides of the equation

$sqrt(k^2= +-sqrt(10.24)$
$k=+-3.2$

There are two possible roots.

Check solution

$+3.2^2=10.24$
$(-3.2)^2=10.24$

$10.24=10.24$
