Question

Se considera expresia
E(x) = (x+1) la puterea a2-a - |x+1|
Calculati E(0) si E(-1)

Answer 1

E(x) = (x+1) ² - |x+1|
E (0 ) = ( 0 + 1) ² - I 0 + 1I = 1² - 1 = 1 -1 = 0 
E (  -1)  = ( -1 + 1) ²  - I -1 + 1 I =  0 + 0 = 0

Answer 2

$E(x)=(x+1)^2-|x+1| \\ E(0)=(0+1)^2-|0+1|=1^2-|1|=1-1=0 \\ E(-1)=(-1+1)^2-|-1+1|=0-0=0$
