2
(xy - 4) ^2 + (2x+2y)^2
It is (2y-2)(2y+2) when factored and is the differebce of two squares
n2 - 4 is the "difference of two squares." That factors to (n - 2)(n+2)a2 + 2a + 1 is "additive squares." That factors to (a + 1)(a + 1) or (a + 1)2
c2 - 6cd + 9d2 - 4 The first three terms are a complete square = (c - 3d)2 - 4 Difference of two squares = (c - 3d + 2)(c - 3d - 2)
Excluding rotations, 2, plus a square.
Area of a Square is given by s^2 (s = length of a side)Using that, the area of one of the small squares is 7^2 = 49cm^2Now, how many of these squares can be cut out of a 240cm^2 square is given by:240/49 = 4, 89 squares = 4 complete squares or Just less than 5 Squares.
(c - 3d - 2)(c - 3d + 2)
(c - 3d - 2)(c - 3d + 2)
x= -10 or 4 most likely 4
The difference of two squares a2 - b2 factors to (a - b)(a + b)
A square covers 100 sq. ft. so 7 squares plus 2 bundles for the starter course and the ridge cap.
