Question

Let T(x)=−6x^4 + x^2 −1 and U(x)=2x^3−4x+3 . Find T(x)−U(x).

Answer 1

To find:

The value of T(x) - U(x).

Solution:

Given that T(x)=−6x^4 + x^2 −1 and U(x)=2x^3−4x+3.

So, T(x) - U(x) can be obtained as follows:

`\begin{gathered} T(x)-U(x)=-6x^4+x^2-1-(2x^3-4x+3) \\ =-6x^4+x^2-1-2x^3+4x-3 \\ =-6x^4-2x^3+x^2+4x-4 \end{gathered}`

Thus, option D is correct.
