Solutia ecuatiei : (x-3)^2=x(x-5)+11 este ..

Answer 1

$\displaystyle (x-3)^2=x(x-5)+11 \\ \\ x^2-2 \cdot x \cdot 3+3^2=x^2-5x+11 \\ \\ x^2-6x+9=x^2-5x+11 \\ \\ x^2-6x-x^2+5x=11-9 \\ \\ -x=2 \\ \\ x=-2$

Answer 2

$6x+9=5x+11==\ \textgreater \ 5x-6x=11-9=2====\ \textgreater \ x=-2$[tex] x^{2} -6x + 9 = x^{2} -5x +11 [/tex]
