Answer 2

Answer:

$A=2x^{4}+2x^{2}-5x+6$

Step-by-step explanation:

In the given question,

We have been provided that,

$(2x^{4}+4x^{2}-3x+7)-A=3x^{2}-x^{2}+2x+1$

Here,

'A' is the value that is subtracted from the given term to get the other term.

So,

On taking the terms left and performing the operation we get,

$(2x^{4}+4x^{2}-3x+7)-A=3x^{2}-x^{2}+2x+1\\A=(2x^{4}+4x^{2}-3x+7)-(3x^{2}-x^{2}+2x+1)\\A=2x^{4}+4x^{2}-3x^{2}+x^{2}-3x-2x+7-1\\A=2x^{4}+2x^{2}-5x+6$

Therefore, we have the value of the A which is needed to be subtracted from the previous equation to get the another term.

So,

$A=2x^{4}+2x^{2}-5x+6$
