You must use the difference of squares formula: x2 - y2 = (x + y)(x - y) Thus: x2 - 25 = (x + 5)(x - 5).

(x+1)(x-1)

Factor out the GCF and get X(X2-X+1).

X2+y2=25 (x-8)2+y2 =41

(x - 1)(x + 1)

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

well, i believe it goes like this (not certain) 25 is the only not prime number so... 3xcubed x squared -5 squared

x(x - 25)(x - 25)

25 squared is 25 x 25 or 625.

25 squared= 25 X 25 = 625 625 X 30 = 18750

There is a formula for the "difference of squares." In this case, the answer is (8x + 5y)(8x - 5y)
