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).
(x - 3)(x + 8)
(x - 1)(x + 1)
(x-5i)(x+5i)
( x^2 - 25 ) = ( x + 5 ) ( x - 5 ) <--------------------------
(x + 5)(x + 5)
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)
(5x - 6)(5x + 6)
(x)(x)
25 squared is 25 x 25 or 625.
25 squared= 25 X 25 = 625 625 X 30 = 18750
(x^2 - 3x + 5)(x^2 + 3x + 5)
You must use the difference of squares formula: x2 - y2 = (x + y)(x - y) Thus: x2 - 25 = (x + 5)(x - 5).
