Question

if the poly.x^4-6x*+16x^2-25x+10 is divided by another poly.x^2-2x+k,the remainder comes out to be x+a,find k and a

Answer 1

what's that star * in .x^4-6x*+16x^2-25x+10

Answer 2

cube

Answer 3

x^4-6x*+16x^2-25x+10
Doing synthetic division you'll get the remainder
(-9+2k)x+10-8k+k^2

Answer 4

given remainder = x + a
so,
x+a = (- 9 + 2k)x + 10 – 8k + k
Comparing coefficients of x on both sides
1 = - 9 + 2k
or 2k = 10
or k = 5
Comparing constants on both sides
10 – 8k + k^2=a
10-8(5)+5^2=a
a=-5

Answer 5

hypothetical question @parvathysubhash
