Question

please/thanks! the area of a square tile is (4x^2+20x+25) in^2. find the length of the tile.

a: (2x+5)in
b: (4x+5)in
c: (16x+25)in
d: (2x+25)in

Answer 1

You know the area is L*W, so take this quadratic and factor it, this will give you two elements where one will be your length and one will be your width. (hint: It's a square so they will be the same)
