Find the Constant Term c in y = 3x² + 5: Quadratic Equation Analysis

Question

a = coefficient of x²

b = coefficient of x

c = coefficient of the independent number


what is the value of c c in this quadratic equation:

y=5+3x2 y=5+3x^2

Video Solution

Solution Steps

00:00 Find coefficient C
00:03 We'll use the quadratic equation formula
00:08 We can see that coefficient C is of the independent number
00:20 If we don't have the X term, it's multiplied by 0
00:27 We'll compare the formula to our equation and find the coefficients
00:42 And this is the solution to the question

Step-by-Step Solution

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

  • Step 1: Compare the given equation y=5+3x2 y = 5 + 3x^2 to the standard form ax2+bx+c ax^2 + bx + c .
  • Step 2: Identify the terms corresponding to a a , b b , and c c .

Now, let's work through each step:
Step 1: The given equation is y=5+3x2 y = 5 + 3x^2 . Rearranging it in the standard form, we have y=3x2+0x+5 y = 3x^2 + 0\cdot x + 5 .

Step 2: From this arrangement, it's clear that:
- a=3 a = 3 (the coefficient of x2 x^2 )
- b=0 b = 0 (there is no x x term, so its coefficient is 0)
- c=5 c = 5 (the constant term)

Therefore, the value of c c is  c=5\ c=5 .

Answer

c=5 c=5
