Answer: 10
Step-by-step explanation:
1 is the awnser to this problem
Consider the expression

Factorize the numerator and denominator a difference/sum of cubes:

Expand the denominator:

since <em>x</em> = 2020, and clearly 2020² + 2020 + 1 ≠ 0, so we can cancel the factor of <em>x</em> ² + <em>x</em> + 1. This leaves us with

so that <em>a</em> + <em>b</em> = 673 + 674 = 1347.
X = 4 AND x = -9
Good luck.
