00:05 First, let's find the function coefficients.
00:08 We will use the formula for representing a quadratic equation.
00:16 Now, arrange the equation so it matches our formula.
00:40 Be sure to separate the variable from its coefficient.
00:53 Compare this formula to our equation, and identify the coefficients.
01:02 And that's how we solve this problem!

Step-by-Step Solution

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

  • Step 1: Express the given quadratic function y=5x3x2 y = 5x - 3x^2 in the standard form.
  • Step 2: Compare the given function with the standard form y=ax2+bx+c y = ax^2 + bx + c .
  • Step 3: Match the coefficients to find the values of a a , b b , and c c .

Now, let's work through each step:

Step 1: The given function is y=5x3x2 y = 5x - 3x^2 .

Step 2: We need the function in the form y=ax2+bx+c y = ax^2 + bx + c . Reordering terms gives us y=3x2+5x y = -3x^2 + 5x .

Step 3: Comparing y=3x2+5x y = -3x^2 + 5x to y=ax2+bx+c y = ax^2 + bx + c , we identify:

  • The coefficient of x2 x^2 is a=3 a = -3 .
  • The coefficient of x x is b=5 b = 5 .
  • The constant term (often written last) is c=0 c = 0 since no constant term is present.

Therefore, the solution to this problem is the coefficients identified as a=3 a = -3 , b=5 b = 5 , and c=0 c = 0 .

Answer

a=3,b=5,c=0 a=-3,b=5,c=0
