Answer:
-6n^4 -5n^3 +13n^2 +2n +3
organize the exponents from higher to lower.
 
        
             
        
        
        
since by the provided tickmarks WE ≅ ER, and QE ≅ ET, then both triangles are congruent by LL theorem, Leg Leg.
anyhow, since those legs are congruent, their hypotenuses must also be congruents, and we could use the HL theorem as well.
