I need help with factoring this expression.

X^2 + 2X + 48 =

X^2 + 2X + 1 = -47

( X + 1 ) ^2 +47 =

( X +1 + i √47) ( X +1 - i√47)

x^{2} + 2x + 48

As written, the equation does not factor. In fact, using the quadratic formula, it has complex roots:

x = -1 ± i√47

If the equation is really x^{2} - 2x - 48, the factors are (x+6)(x-8)

If it's really x^{2} + 2x - 48, the factors are (x-6)(x+8)
