Question

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

Answer 1

Answer:

Step-by-step explanation:x=-2

X=3

So putting the value in the eq.

2*-8 -3*-4 -11*-2 +6

-16 -12 +22 +6

-28 +28

=0

Putting x=3

2*27 - 3*9 -11*3 +6

54 -18 -33 +6

60-51=9

Therefore -2 is only zero

Answer 2

Answer: NO

Step-by-step explanation:

1.) Put the value of x as (-2) in the equation.

• 2(-2)*3 - 3(-2)*2 - 11(-2) + 6

•       -12 + 12 + 22 + 6
•              28    

~ Since, the answer is not zero, (-2) is not a zero of the polynomial.

2.) Put the value of x as 3 in the polynomial.

• 2*3*2 - 3*3*2 - 11*3 + 6
•      12 - 12 - 33 + 6
•             -27

~ Since the answer is not zero, 3 is not a zero of the polynomial.
