how can I solve this quadratic equation​


Sagot :

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.
