Answer 1

Answer:

Answer :

= 2x³– 9x²+x+12

= 2x–3=0

= 2x=3

= x = 3/2

=2(3/2)³ – 9(3/2)² + 3/2 + 12

=2(27/18) – 9(9–4) + 3/2 + 12

= 27/4 –81/4 + 3/2 + 12

=27–81 + 6 + 48/4

=81 –81/4

=0/4

=0

Answer =0

I hope this is helps you.

Answer 2

Answer:

=>2x-3=0

=>2x=3

=>x=3/2

=>x+2x^3-9x^2+12

=>2x^3-9x^2+x+12

=>2×(3/2)^3-9×(3/2)^2+3/2+12

=>2×27/8-9×9/4+3/2+12

=>27/4-81/4+3/2+12

27-81+6+48

=>__________

4

81-81

=>_______

4

=>0/4

=>0

hence,

(2x-3) is a factor of polynomial x+2x^3-9x^2+12
