Question

identify the correct list of coefficients for the quadratic expression 7x to the second power - 4x + 12

7, -4
7x to the second power, -4x
7x to the second power, -4x, 12
7, -4, 12

Answer 1

The quadratic expression \( 7x^2 - 4x + 12 \) can be analyzed for its coefficients. The standard form of a quadratic expression is \( ax^2 + bx + c \), where:

- \( a \) is the coefficient of \( x^2 \)
- \( b \) is the coefficient of \( x \)
- \( c \) is the constant term

In the expression \( 7x^2 - 4x + 12 \):

- \( a = 7 \)
- \( b = -4 \)
- \( c = 12 \)

Thus, the complete list of coefficients is \( 7, -4, 12 \).

The correct answer from the options given is:

**7, -4, 12**
