Question

find the remainder when x cube minus 3 X square + 2 X + 3 is divided by 2 X + 3​

Answer 1

Step-by-step explanation:

f (x)=x^3-3x^2+2x+3

f (x)=2x+3

f (x)=-3/2

f (-3/2)=(-3/2)^3- 3 (-3/2)^2+2 (-3/2)+3

f (-3/2)=-27/8-3 (-9/4)+2 (-3/2)+3

f (-3/2)=(-27/8)+27/4+0

f (-3/2)=(-27/8)+54/8+0

f(-3/2)=27/8

The remainder is 27/8
