SOLUTION: I am supposed to solve: x^2+14x-4=0 Is the answer x=0.28,14.28 I don't think that's right

You can put this solution on YOUR website!
YES.
--------------------
x^2+14x-4=0

x=(-14+-sqrt[14^2-4*1*-4])/281
x=(-14+-sqrt[196+16])/2
x=(-14+-sqrt212)/2
x=(-14+-14.56)/2
x=(-14+14.56)/2
x=.56/2
x=.28 ans.
x=(-14-14.56)/2
x=(-28.56)/2
x=-14.28 ans.

Is the answer x=0.28,14.28
I don't think that's right

Checkley said yes, so let's find out for sure:

 

with , , 

 

 





 







Using the +,



Using a calculator:



That rounds off to 0.28, so you're right on that one.


Using the -,



Using a calculator:



That rounds off to -14.28.  Uh oh! You missed the
sign on that one. Checkley didn't notice.
But you were half right!
