Answer:
Start with the equation:
2
−
196
=
0
K
2
−196=0
Add 196 to both sides to isolate the term with
K:
2
−
196
+
196
=
0
+
196
K
2
−196+196=0+196
2
=
196
K
2
=196
Take the square root of both sides to solve for
K. Remember to consider both the positive and negative square roots:
2
=
±
196
K
2
=±
196
=
±
196
K=±
196
Simplify
196
196
:
196
=
14
196
=14
So:
=
±
14
K=±14
Write the solutions:
=
14
or
=
−
14
K=14orK=−14
Thus, the solutions to the equation
2
−
196
=
0
K
2
−196=0 are
=
14
K=14 and
=
−
14
K=−14.
