I need help with factoring this expression.
Tutors, please sign in to answer this question.
X^2 + 2X + 48 =
X^2 + 2X + 1 = -47
( X + 1 ) ^2 +47 =
( X +1 + i √47) ( X +1 - i√47)
x2 + 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 x2 - 2x - 48, the factors are (x+6)(x-8)
If it's really x2 + 2x - 48, the factors are (x-6)(x+8)
