Question

What is the difference of the polynomials? (X^4+x^3x+^2+x)-(x^4-x^3-x^2-x)

Answer 1

`\bf (x^4+x^3+x^2+x)~~-~~(x^4-x^3-x^2-x) \\\\\\ (x^4+x^3+x^2+x)~~~~-x^4+x^3+x^2+x \\\\\\ x^4+x^3+x^2+x~~-~~x^4+x^3+x^2+x \\\\\\ x^4+x^3+x^2+x-x^4+x^3+x^2+x \\\\\\ \underline{x^4-x^4}+x^3+x^3+x^2+x^2+x+x\implies 2x^3+2x^2+2x`
