Question

what is the missing term? -4 -16x 4 x? -x 4x -1

Explanation:

Step1: Analyze the relationship in the first - row

In the first row, when we consider the first - column element $-16x$ and the first - row multiplier $- 4$, we can find the relationship by division. If we divide $-16x$ by $-4$, we get $4x$. Also, when we divide the second - column element $4$ in the first row by $-4$, we get $-1$.

Step2: Calculate the missing term

Since the multiplier for the second row is $x$, and the corresponding multiplier for the first column is $4x$. To find the missing term, we multiply $x$ and $4x$. According to the rule of multiplying variables ($a^m\times a^n=a^{m + n}$), when we multiply $x$ and $4x$, we get $4x^2$.

Answer:

$4x^2$
