Question Which quadratic expression is in standard form? a. $(x+3)x$, b. $(x+4)^2$, c. $-x^2-5x+7$, d. $x^2+2(x+3)$

Studdy Solution
Identify the option(s) that are already in standard form.
Options b, c, and d are in standard form. However, the question asks for the quadratic expression that is written in standard form, implying the one that is in standard form without further manipulation. Option c is in standard form without any need for expansion or simplification.
The quadratic expression written in standard form is: c. $-x^{2}-5 x+7$
