Remember: sqr(b)*sqr(b) = b

Ya Sledge.....but wanted him to get that far and ask the ?

I am amazed that I can still recall this being I graduated from HS in 1962!
College in 71 with serving our country in between.

...Question 'b' is harder how do I just get the 'b' from the sqr(b)? Hmm

Picture it using actual numbers.

If you had sqr(9) on one side, what then?
Square both sides. Your sqr(9) magically becomes just "9", because:

sqr(9) X sqr(9) = 9

Remember what BugMeister said:

...what you do to one side of the equation, you must also do to the other...

Whatever is on the other side is also squared and becomes {itself} X {itself}

Clicked the wrong thing while replying and had to start over. It took you a lot less words to say what I was trying to tell him. :)

Math is just a set of rules. Play the game right and use the rules in their proper order and you'll win every time.

(Easier said than done, I know.)

It's no fun, but LOTS of practice is the best idea. You wouldn't shoot one free throw, sink it, then decide you had it down pat. But doing it over and over and over and...

What? Don't they play basketball in Wisconsin?
