Factorize x power of 3 - 3x power of 2 -9x - 5 |
|
Answer» Step-by-step explanation: x³ - 3x² - 9X - 5 = x³ + x² - 4x² - 4x - 5X - 5 = x²( X + 1) - 4x ( x + 1) - 5(x + 1) = (x + 1)(x² - 4x - 5) = (x + 1)(x² -5x + x - 5) = (x + 1)(x - 5) (x + 1) HENCE, (x +1), (x -5) and (x +1) are the factors of given POLYNOMIAL. |
