Find all real values of t that satisfy the equation t^2 = 196.

-2

Since t^2 = 196,

 

applying sqrt to both sides give

 

t = sqrt(196)

 

HOWEVER there is another answer that satisfies this... can you find it?

 

HINT: think of pos/neg multiplication

 

If you don't understand anything feel free to ask.
