exactly divisible by (x-2) is:

Answer

• see the achievement
• P = 16 Ans

Answer 2

Answer:

i can aswer that.

Step-by-step explanation:

1

Let f(x)=ax3+8x2+bx+6 , and let g(x)=x2−2x−3. Since the question says that g(x)|f(x), then write f(x)=g(x)(px+q). Note the linear polynomial, we did that because dividing f(x) by g(x) will result in degree 1. Now, expand the LHS and RHS, and you get something like this:

ax3+8x2+bx+6=(x2−2x−3)(px+q)=px3+x2(q−2p)−x(2q+3p)−3q

Clearly, q=−2, and p=−5. Now get the values of a and b by comparing the co-efficients.
