Video Solution

Solution Steps

00:00 Find coefficient C
00:03 We'll use the quadratic equation formula
00:09 Let's compare the formula to our equation and find the coefficients
00:19 We can see that coefficient C is of the independent number
00:23 And this is the solution to the question

Step-by-Step Solution

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

  • Identify the given quadratic equation.
  • Compare the given equation with the standard quadratic form ax2+bx+c ax^2 + bx + c .
  • Determine the value of c c by direct comparison.

Now, let's work through each step:
Step 1: The given quadratic equation is y=5x2+4x3 y = -5x^2 + 4x - 3 .
Step 2: The standard form of a quadratic equation is ax2+bx+c ax^2 + bx + c . We need to match the coefficients accordingly.
Step 3: By comparing the terms from the equation with the standard form, a a is the coefficient of x2 x^2 , b b is the coefficient of x x , and c c is the constant term or the independent number.

Therefore, from the equation y=5x2+4x3 y = -5x^2 + 4x - 3 :

  • a=5 a = -5
  • b=4 b = 4
  • c=3 c = -3

Thus, the value of c c in the quadratic equation is c=3 c = -3 .

Answer

c=3 c=-3
