Question

find the name of a, if 2x-3 is a factor of 2x^4-x^3-3x^2-2x+9.​

Answer 1

Answer:

Step-by-step explanation:

let p(x)= 2x^4-x^3-3x^2-2x+9

then, g(x)= 2x-3

if g(x)= 0

 2x-3=0

 2x=3

 x=3/2

p(3/2)= 2×(3/2)^4-(3/2)³-2×3/2+9

0= 2×729/16-81/8-3+9

0= 729/8-81/8-3+9

0= (729-81-24+72)/8

0= 694
