Answer:
Step-by-step explanation:
(x+2) is factor of mx^3+nx^2+x-6.it leaves the remainder 4 when divided by (x-2).find m and n
SEE ANSWER
Since x+2 is a factor of the polynomial p(x) .
Therefore => x+2=0
=> x=-2
Putting the value of x in the given equation we get .
-8m+4n=8 (a)
Similarly when polynomial p(x) is divided by (x-2) leaves remainder 4.
=> x-2=0
=> x=2
Now putting the value of x in the given equation we get .
8m+4n-4=4
=>8m+4n=8. (b)
hence equate equations a and b you will get the value of m and n
