(x-5i)(x+5i)
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
(x + 5)(x + 5)
x(x - 25)(x - 25)
(x^2 - 3x + 5)(x^2 + 3x + 5)
If x is equal to 5, then x squared plus 25 is equal to 50.
(a + x^2)(b + y^2)
No
x2y + axy + abx + a2b Factor by grouping. xy(x + a) + ab(x + a) (xy + ab)(x + a)
(5 - x)(5 + x)
(x + 3)(x + 3)
(x + 2)(x + 1)
(x+1)(x+8)
