? Learn how to find the value c that completes the square in a quadratic expression. A quadratic expression is an expression whose highest exponent in the variable(s) is 2. It is of the form ax^2 + bx + c where a, b, and c are constants. The value c that we create is what will turn our quadratic expression into a perfect square trinomial. A perfect square trinomial is an expression that can be expressed in the form (x + a)^2.

Given a quadratic expression, ax^2 + bx + c, the value of c that completes the square in the quadratic expression is given by c = (b/2)^2.

Thank you very much for taking the time to make this video. I really needed it for my Summer Math! :)

Thanks! Your videos are extremely helpful. I had a poor foundation in math, which hurts me presently, so 45 mins. of math in the classroom isn't long enough to teach me the lesson that's being presented that day. Watching these videos on YT helps so much, especially when I'm not distracted by outside disturbances. Again, thank you.

In this video we work an

In this video we work an example in which we're given a function of x involving the constant c. We have to figure out what value of c will make the function continuous for all values of x.

Thank you for making this painless

aight i gotta make sure i mention your name in my graduation speech. thanks

Brenden Draper

What value(s) of the constant c makes the function
f(x) =  c2 ? x2 if x < 2
          2(x + c) if x  2
continuous on R? 

Please assist ???

Danny !

you make sense to me. thank you!!

Fish

Thank you for never explaining why polynomial functions are always continuous at 0

Jack Lara

Wouldn't it be -2c^2? at 3:43...
