Question

verify if -2 and 3 are zeroes of the polynomial 2x^3-3x^2-11x+6 . If yes factorise the polynomial

Answer 1

2x^3 - 3x^2 - 11x + 6
Now,
2*(-2)^3 -3*(-2)^2 - 11*(-2) + 6
2*(-8) - 3*4 + 22 + 6
-16 - 12 + 28
-28 + 28
0
Again,
2*3^3 - 3*3^2 - 11*3 + 6
2*27 - 3*9 - 33 + 6
54 - 27 - 27
54 - 54
0

Answer 2

Answer:

answer is given below;

Step-by-step explanation:

2x^3 - 3x^2 - 11x + 6

Now,

2*(-2)^3 -3*(-2)^2 - 11*(-2) + 6

2*(-8) - 3*4 + 22 + 6

-16 - 12 + 28

-28 + 28

0

Again,

2*3^3 - 3*3^2 - 11*3 + 6

2*27 - 3*9 - 33 + 6

54 - 27 - 27

54 - 54
