If (x+1) is factor of ax^(3)+bx^(2)+cx+d then the condition is A ) a+b = c+dB ) a+c = b+dC ) a+b+c+d = 0D ) a+b+c+d = 1 |

Answer» If x2 + x + 1 is a FACTOR of ax3 + bx2 + cx + d, then the REAL root of ax3 + bx2 + cx + d = 0 is. (ax3 + bx2 + cx + d) = a [x2 + x + 1] (x – ɑ) where ɑ is a real root of the given equation. |
