1.	What must be added to polynomial 2x^3-3x^2-8x,so that it leaves a remainder 10 when divided by 2x+1
Answer» ANSWER: ADD -3 solution.... f(X)=2x^3-3x^2-8x put x=-1/2. (2x+1=0) f(-1/2)=3 so f(x)-3 is DIVISIBLE by 2x+1

What must be added to polynomial 2x^3-3x^2-8x,so that it leaves a remainder 10 when divided by 2x+1

Answer»

ANSWER:

ADD -3

solution....

f(X)=2x^3-3x^2-8x

put x=-1/2. (2x+1=0)

f(-1/2)=3

so f(x)-3

is DIVISIBLE by 2x+1
