Question

please give me the correct ANSWER​

Answer 1

Answer:

$2x^{4}-6x^{3}+6x^{2}+2x-7+7x^{3}-x-5x^{2}+2-x^{4}$

$=2x^{4}-x^{4}-6^{3}+7x^{3}+6x^{2}-5x^{2}+2x-x-7+2$

$= x^{4}+x^{3}+x^{2}+x-5$

Hence, the simplified form of $2x^{4}-6x^{3}+6x^{2}+2x-7+7x^{3}-x-5x^{2}+2-x^{4}$ is $x^{4}+x^{3}+x^{2}+x-5$

Hope it helps
