Answer 1

Answer:

Step-by-step explanation:

(i). x³ - 2x² - x + 2 = x²(x - 2) - (x - 2) = (x - 2)(x² - 1) = (x - 2)(x - 1)(x + 1)

(ii). x³ - 3x² - 9x - 5 = (x + 1)(  $\frac{x^3 - 3x^2 -9x-5}{x+1}$ ) =  (x + 1)²(x - 5)

(iii). x³ + 13x² + 32x + 20 = (x + 1)( $\frac{x^3 +13x^2 +32x+20}{x +1}$ ) = (x +)(x² + 12x + 20) = (x + 1)(x + 2)(x + 10)

(iv). y³ + y² - y - 1 = y²(y + 1) - (y + 1) = (y + 1)(y² - 1) = (y + 1)²(y - 1)
