(2x - 5)(2x - 5)
64x2-80x+25 = (8x-5)(8x-5) when factored
49x²+70x+25 = (7x+5)² since the root (-70/(2*49)) of the quadratic equations is -5/7 (discriminant = 70²-4*49*25 = 0)
16x2 + 40x + 25 = 16x2 + 20x + 20x + 25 = 4x(4x + 5) + 5(4x + 5) = (4x + 5)(4x + 5) = (4x + 5)2

x2 + 10y + 25 doesn't factor neatly. If that was x2 + 10x + 25, it would factor to (x + 5)(x + 5) or (X + 5)2
