Question

FIND THE FACTORIZATION
$x {}^{3 } - 3x { }^{2} - 9x - 5$

​

Answer 1

Question:-

➡ Factorise x³ - 3x² - 9x - 5

Solution:-

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(x - 5) + 1(x -5))

= (x + 1)(x + 1)(x + 5)

= (x + 5)(x + 1)²

Hence, the factorised form is (x + 5)(x + 1)²

Answer:-

➡The factorised form is (x + 5)(x + 1)²
