Question

Which quadratic expression is written in standard form?

A. (x+3)x
B. (x + 4)
C. -x^2 - 5x + 7
D. x + 2(x + 3)

Answer 1

The quadratic expression written in standard form is -x^2 - 5x + 7.

Step-by-step explanation:

The quadratic expression that is written in standard form is C. -x^2 - 5x + 7.

In standard form, a quadratic expression is written as ax^2 + bx + c, where a, b, and c are constants.

In this case, the expression -x^2 - 5x + 7 has the leading coefficient a as -1, the linear coefficient b as -5, and the constant term c as 7, so it is written in standard form.
