Question

if polynomial x²
+ 6x²-25x+10 is divided by another polynimal x²-2x+k the
remainder comes out to be x+a
then find k & a


pls very argent​

Answer 1

Answer:

Given that the remainder is (x + a)

⇒ (4k – 25 + 16 – 2k)x + [10 – k(8 – k) ] = x + a  

⇒ (2k – 9)x + [10 – 8k + k2 ] = x + a

On comparing both the sides, we get

2k  – 9 = 1

⇒ 2k = 10

∴ k = 5

Also 10 – 8k + k2 = a

⇒ 10 – 8(5) + 52 = a

⇒ 10 – 40 + 25 = a

∴ a = – 5
