144x2 - 25
64x2-80x+25 = (8x-5)(8x-5) when factored
It is 205 minus 25 = 180
52 = 25
The answer is 25. This is because five to the second power is just like saying 5x5. All you need to do is five to the second power BAM! Two fives 5x5!

64x2-80x+25 = (8x-5)(8x-5) when factored
4x2-20+25 = (2x-5)(2x-5) when factored with the help of the quadratic equation formula.
x2 - 25This expression is the difference of squares. Thus:x2 - 52(x + 5)(x - 5).
25-2 = 1/(252) = 1/625
25
5 to the second power = 5*5 = 25
v2 - 25 = (v + 5)(v - 5) [difference of two squares]
25
25
Minus 25 (5x5=25 if there is one minus then the answer is minus).
1/25
