उत्तर
Let us denote the given polynomials as
`f(x) = x^4 - 3x^2 + 4,`
`g(x) = x-2`
We have to find the remainder when f(x) is divided by g(x).
By the remainder theorem, when f(x)is divided by g(x) the remainder is
`f(2) = (2)^4 - 3 (2)^2 + 4`
` = 16 - 12 + 4`
` = 8`
We will calculate remainder by actual division

So the remainder is 8
