Question

Buna,vreau ajutor la E(x) ma chinui de jumatate de ora si nu l am rezolvat.Daca stiti si punctul b puteti sa mi l scrieti dar ma intereseaza doar E(x) si rezolvarea.Multumesc anticipat

Answer 1

Răspuns:

$a)$

$2(x-1)^2+(3x+2)^2-10(x-3)(x+3)-96$

$2(x^2-2x+1)+9x^2+12x+4-10(x^2-9)-96$

$2x^2-4x+2+9x^2+12x+4-10x^2+90-96$

$x^2+8x$

$b)$

$E(2^2^0^2^1):4^1^0^1^2$

$E(2^2^0^2^1)=(2^2^0^2^1)^2+8*2^2^0^2^1$

$=2^4^0^4^2+2^3*2^2^0^2^1$

$(2^2)^2^0^2^1+2^2^0^2^4$

$4^2^0^2^1+(2^2)^1^0^1^2$

$4^2^0^2^1+4^1^0^1^2$

$4^1^0^1^2(1+4^1^0^0^9)$

$=> E(2^2^0^2^1):4^1^0^1^2$ este adevarat
