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.
