Question

a = coefficient of x²

b = coefficient of x

c = coefficient of the independent number


what is the value ofb b in this quadratic equation:

y=4x216 y=4x^2-16

Video Solution

Solution Steps

00:00 Find coefficient B
00:03 We'll use the quadratic equation formula
00:07 We can see that coefficient B is for the X term
00:15 In this equation we don't have an X term, meaning it's multiplied by 0
00:19 Let's compare the formula to our equation and find the coefficients:
00:31 And this is the solution to the question

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Identify the given information and the standard quadratic form
  • Compare the given equation to this standard form
  • Extract the coefficients a a , b b , and c c and find b b

Now, let's work through each step:
Step 1: The problem provides us with the equation y=4x216 y = 4x^2 - 16 . It's already in a form where we can identify the coefficients.
Step 2: Recall the standard form of a quadratic equation is ax2+bx+c ax^2 + bx + c . Compare this form to the equation y=4x216 y = 4x^2 - 16 .
Step 3: By comparison, the coefficient of x2 x^2 (which is a a ) is 4. There is no x x term explicitly present, implying that b=0 b = 0 . The constant c c is -16.
Therefore, after comparison and identification, it becomes clear that the value of b b in the equation is b=0 b = 0 .

Answer

b=0 b=0
