I need help with factoring this expression. May 7 | LaRoma from Dayton, OH | 2 Answers | 0 Votes Mark favorite Subscribe Comment Comments The equation does not factor as written. In fact, the roots are complex numbers. Are you sure it's not -2x vice +2x or -48 vice +48? May 7 | Philip P. Hi Phillip, the question just says to factor the expression, and some examples of the answers are (x+1)(x+48),(x+8)^2,(x+8)(x+16), or prime polynomial. May 7 | LaRoma from Dayton, OH Comment

X^2 + 2X + 48 = X^2 + 2X + 1 = -47 ( X + 1 ) ^2 +47 = ( X +1 + i √47) ( X +1 - i√47) May 7 | Parviz F. Comment
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) May 7 | Philip P. Comment
