4x2-20+25 = (2x-5)(2x-5) when factored with the help of the quadratic equation formula.
25
5 to the second power = 5*5 = 25
Minus 25 (5x5=25 if there is one minus then the answer is minus).
25
144x2 - 25
It cannot be simplified any further so it is: 10c - 25
64x2-80x+25 = (8x-5)(8x-5) when factored
20 over 13
4x2-20+25 = (2x-5)(2x-5) when factored with the help of the quadratic equation formula.
2^25
25-2 = 1/(252) = 1/625
25
5 to the second power = 5*5 = 25
A square number is a number that can be simplified to another number raised to the second power. For example 25, is 5^2, 16 is 4^2, 9 is 3^2 and so on.
v2 - 25 = (v + 5)(v - 5) [difference of two squares]
That depends on the plus or minus value of 25 but --21 is the same as +21
