Explicación paso a paso:
A) 3x^2+5x-11, x=2
3(2)^2 +5(2)-11
3(4)+10-11
12-1=11
B) 3x+5y
3(4)+5(2)
12+10
=22
C) 3b^2 c
3(3)^2 (4)
3(9)(4)
=108
D) (4/6)^2
(2/3)^2
=4/9
POLINOMIOS
A) 4a,-8b,-15a,9b,-4c,8
=4a-14a-8b+9b-4c+8
= -10a+b-4c+8
B) 5x,9xy,-6xy, 7y,8x
5x+8x+9xy-6xy+7y
=13x+3xy+7y
C) 8a-3b+5c-d, - 2b+c-4d, - 3a+5b-c
8a-3a-3b-2b+5b+5c+c-c-d-4d
5a+5c-5d
Si a=1,b=2,c=3,d=4
5(1)+5(3)-5(4)
5+15-20
=0
ACTIVIDAD DE APRENDIZAJE 5
A) - 4-7= -11
