Question

identify the correct list of coefficients for the quadratic expression 7x^2 - 4x + 12

Answer 1

The coefficients of the quadratic expression \( 7x^2 - 4x + 12 \) can be identified as follows:

- The coefficient of \( x^2 \) (the quadratic term) is **7**.
- The coefficient of \( x \) (the linear term) is **-4**.
- The constant term (the term without \( x \)) is **12**.

So the correct list of coefficients is:

- **7** (for \( x^2 \))
- **-4** (for \( x \))
- **12** (constant term)

In summary, the coefficients are: **7, -4, 12**.
