Answer

3x2−2x−2

Explanation
Based on the given conditions, formulate:
(2x2−6x−2) + (x2+4x)

Remove the parentheses:
2x2−6x−2+x2+4x

Reorder and gather like terms:
(2x2+x2) + (−6x+4x)−2

Collect coefficients for the like terms:
(2+1) x2 + (−6+4)X x−2

Calculate the sum or difference:
3x2+ (−6+4)X x−2

Calculate the sum or difference:
3x2−2x−2
