Divide.<br> (4x4 - 4x2 – x-3) = (2x2 – 3)

inn [45]

Given:

Division problem:

$(4x^4-4x^2-x-3)\div (2x^2-3)$

To find:

The solution for the given division problem.

Solution:

We have,

$(4x^4-4x^2-x-3)\div (2x^2-3)$

Here, 4x^4-4x^2-x-3 is the dividend and (2x^2-3) is divisor.

Using the long division method we get

$\underline{2x^2-3}|\overline{4x^4-4x^2-x-3}|\underline{2x^2+1}$

$\underline{4x^4-6x^2}$

$2x^2-x-3$ (After subtraction)

$\underline{2x^2\quad \quad -3}$

$\underline{\quad -x\quad}$ (After subtraction)

Now,

$\dfrac{4x^4-4x^2-x-3}{2x^2-3}=2x^2+1-\dfrac{x}{2x^2-3}$

Therefore, the required solution is $2x^2+1-\dfrac{x}{2x^2-3}$ .
