Okay, let's start from the beginning. You may take coefficient of a term as the number before the term. For example coefficient of x in the term 8x is 8. Now, in your question, the term is 2x^2. Can you identify the coefficient of x^2?

No...

By the way, it's b^2 - 4ac, not b^2 - 4ab

The coefficient is the constant multiple

constants are numbers that don't change

Including?

8x 8 is a constant x is a variable and actually 8 here is a constant multiple and is therefore the coefficient of x
freckles
  • freckles
8 here is called a constant multiple because it is being multiply by that variable

So in 2x^2 What is the coefficient of x^2?
