the area of a rectangle is x^4+10x^2+9. what is its width

Question

 this is for my algebra 2 online class. i'm a freshman in college so its a college level class (obviously) but i cant find where to figure this particular question out?? help!!!

Answer 1

Assuming that the area, length times width = x⁴+10x²+9=(x²+9)(x²+1) and assuming that one of these factors is the height and the other the width, and that the width is the larger number, then it is x²+9 which is, for any real number greater than x²+1
