Question

Divide and verify the results:
(a) 3x3 – 5x2 - 11x – 3 by (x – 3)​

Answer 1

Step-by-step explanation:

3x³-5x²-11x-3

=. 3x²(x-3)+4x(x-3)+1(x-3)

= (x-3) (3x²+4x+1)

if devide x-3 then result will be (3x²+4x+1)

Answer 2

Step-by-step explanation:

method 1

______________

x-3. | 3x³-5x²-11x-3. |. 3x²+4x+1

3x³-9x²

– +

––––––––––––

4x²-11x-3

4x²-12x

– +

––––––––––––

x-3

x-3

– +

–––––––––––

0

method 2

take x-3=0

x=3

now put value of x in the polynomial

3x³-5x²-11x-3

3*27-5*9-11*3-3

81-45-33-3

81-81
