Identify Coefficients in 10x²+20x+5=0: Finding a, b, and c Values

To determine the components of the quadratic equation, follow these steps:

• Step 1: Recognize the standard form of a quadratic equation, which is $ax^2 + bx + c = 0$.
• Step 2: Compare the given equation $10x^2 + 20x + 5 = 0$ to the standard form.
• Step 3: Identify the coefficients:
  - The term $10x^2$ indicates that $a = 10$.
  - The term $20x$ indicates that $b = 20$.
  - The term $5$ is the constant term, so $c = 5$.

Therefore, the components of the equation are:

$a = 10$, $b = 20$, $c = 5$.

The correct answer among the choices provided is the one that correctly identifies these coefficients:

$a=10$ $b=20$ $c=5$

Therefore, the correct choice is Choice 4.
