If the area of square ABCD is 16x^2 - 52x + 49 then find length of AB.

Answer 1

The side of a square is the square root of the area. So take the area (16x² - 52x + 49) and take the square root. Of course, as is, that isn't easy, but if you factor it, it becomes (4x - 7)² then you can take the square root. (4x - 7). So the length of AB is 4x - 7
