Question

Solve x^5 - 8x^4 + 22x^3 - 26x^2 + 21x - 18 -0.

Answer 1

= x^5 - 8x^4 + 22x^3 - 26x^2 + 21x - 18

Explanation:

x^5 - 8x^4 + 22x^3 - 26x^2 + 21x - 18 - 0

Since all the exponents have different bases, the only thing we can do is subtract 18 from 0, which gives us an answer of:

= x^5 - 8x^4 + 22x^3 - 26x^2 + 21x - 18
