Example Question - quadratic expression coefficient

Determination of Quadratic Expression Coefficient

The general form of a quadratic expression is \( ax^2 + bx + c \). Given the quadratic expression \( 4 - 3x - 2x^2 \), we need to compare this with the general form to find the value of \( a \). First, rearrange the given expression to match the general form: \( -2x^2 - 3x + 4 \) Now, we can see that \( a \), the coefficient of \( x^2 \), is \( -2 \). Therefore, the value of \( a \) is \( -2 \), which corresponds to option C.
