Respuesta:
1. 8x²+8x+3
2. 10x+4
3. -3m-7mn-4n
4. 6a²+2a-5ab-7b²+7
5. 5x²+9xy+5
SUMAS DE POLINOMIOS:
1.- Sumar 5x²+6x+7 con 3x²+2x-4=
(5x²+6x+7)+( 3x²+2x-4)=
(5x²+3x²)+(6x+2x)+(7-4)=
8x²+8x+3
2.- Sumar 2(3x+3) con 2(2x-1)=
2(3x+3)+ 2(2x-1)=
(6x+6)+ (4x-2)=
(6x+4x)+(6-2)=
10x+4
3.- Sumar -9m+2mn-7n con 6m-9mn+3n=
(-9m+2mn-7n)+ (6m-9mn+3n)=
(-9m+6m)+(2mn-9mn)+(-7n+3n)=
-3m-7mn-4n
4.- 6a²-4a+2ab-5b² con 6a-7ab-2b²+7=
(6a²-4a+2ab-5b²)+(6a-7ab-2b²+7)=
6a²+(-4a+6a)+(2ab-7ab)+(-5b2-2b²)+7=
6a²+2a-5ab-7b²+7
5.- 2x²+7xy+3 sumar con 3x²+2xy+2=
(2x²+7xy+3)+( 3x²+2xy+2)=
(2x²+3x²)+(7xy+2xy)+(2+3)=
5x²+9xy+5
