Question

Factories x power3 -3x power2-9x-5

Answer 1

Ans:- 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)

here is your answer

hope it will help you
