Question

$x^3 - 3x^2 - 9x - 5$
please armies solve the equation fast I am confused tomorrow is my paper ​

Answer 1

Answer:

=x³ + x² -4x² - 4x - 5x - 5

= x² ( x+1 ) - 4x ( x + 1 ) - 5 ( x + 1 )

= ( x + 1 ) ( x² - 4x -5 )

= ( x + 1 ) ( x² -5 + x -5 )

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

Step-by-step explanation:

Hence, ( x + 1 ),( x - 5 ) and ( x + 1 ) are the factors of given polynomial
