eliott was trying to factor 6x² - 18. he found that the greatest common factor of these terms was 6 and made an area model: width 6 6x² - 18 what is the width of eliotts area model? width =
Answer
Answer:
$x^{2}-3$
Explanation:
Step1: Recall area - model concept
Area of a rectangle = length×width. Here length = 6, and area = $6x^{2}-18$.
Step2: Use division to find width
Width=$\frac{6x^{2}-18}{6}$.
Step3: Divide each term
$\frac{6x^{2}}{6}-\frac{18}{6}=x^{2}-3$.
