Travis is needing to package a terrain set for a game he sold. He knows that the volume of the rectangular package is modeled by this expression: 3x^2+6x . The length times the width of the package is also modeled by the expression:

x^2+7x+10
. Travis only needs to figure out what the height of the package should be.

Part A: What operation should Travis use to find the height of the package? (2 points)
