As a student, I found that I remembered information a lot easier when the information was in a song. I learned the 'quadratic formula song' in one of my math classes and have not forgotten the formula since. Several of my students have also found this song helpful (and catchy!), so I though I'd share: The 'Quadratic Formula Song' (sung to the lyrics of 'Pop Goes the Weasel') The quadratic formula is negative b plus or minus the square root of b squared minus four a c all over 2a! (Warning, this will get stuck in your head!)
What's happening in the world of private tutoring?

ax^2 +bx + c = 0 Example 7x^2 +12x +16 =0 Don't forget the quadratic formula when you come across a quadratic that CAN'T be factored: x = (-b +/- (sqroot)( b^2 - 4ac))/2a by the way, for those who don't know, I use the ^ sign as my "power" indicator
