Question

(x +2 ) is a factor of mx3 +nx2+x-6. It leaves the remainder 4 when divided by

(x-2). Find m and n.​

Answer 1

Answer:

-1

Step-by-step explanation:

x−2 is factor

⇒x=2

f(2)=14+4m+2n

Remainder is zero

⇒7+2m+n=0⟶(i)

Now, x−3=0

gives remainder 3

⇒f(3)=3

⇒33+9m+3n=3

⇒10+3m+n=0⟶(ii)

From (i) & (ii)

m=−3

n=−1

Answer 2
