Question

By using factor theorem Prove that (x-1) is a factor of (2x4 + 9x3 + 6x2 -11x -6)​

Answer 1

Answer:

2 27. 12. 12. 16

Step-by-step explanation:

2. 27. 12. 16.

Answer 2

Answer:

( x - 1 ) = 0

x = 1

$2 {x}^{4} + 9 {x}^{3} + 6 {x}^{2} - 11x - 6 \\ 2 \times {1}^{4} + 9 \times {1}^{3} + 6 \times {1}^{2} - 11 \times 1 - 6 \\ 2 + 9 + 6 - 11 - 6 \\ 17 - 17 \\ 0$

Since the answer is zero.

Hence ( x - 1 ) is a factor of the given equation.
