    @Makayla43 Time for you to try. What is the coefficient of x^2?

    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?

    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

    8x 8 is a constant x is a variable and actually 8 here is a constant multiple and is therefore the coefficient of x

    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?
