Question

find whether 2a*3+a*2-5a+2 is divisible completely by 2a+3​

Answer 1

Answer:

let p(a)= 2a^3+a^2-5a+2

2a+3=0

2a= -3

a= -3/2

p(-3/2)= 2*(-3/2)^3+(-3/2)^2-5*-3/2+3

= 2*-27/8+9/4+15/2+2

= -27/4+9/4+15/2+2

= -27+9+30+8 divided by 4

= 20/4

= 5

therefore 2a^3+a^2-5a+3 is not completely divisible by 2a+3
