16x2 + 40x + 25
= 16x2 + 20x + 20x + 25
= 4x(4x + 5) + 5(4x + 5)
= (4x + 5)(4x + 5)
= (4x + 5)2

If you mean:0 = 800 - 10x + 25 * 20 = 800-10x+25*210x = 800+50x = 8,50 = 800 - 10x + 25 * x * 20 = 800 - 10x + 50x-800 = 40x-50 = x
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)
