Question

Determinati radacina patrata a solutiei ecuatiei (2x-3)•|8-radical din 65|=5(radical din 65-8)

Answer 1

$(2x-3)|8- \sqrt{65} |=5( \sqrt{65} -8)\ \textless \ =\ \textgreater \ \\ \ \textless \ =\ \textgreater \ (2x-3)( \sqrt{65} -8)=5( \sqrt{65} -8)\ \textless \ =\ \textgreater \ \\ \ \textless \ =\ \textgreater \ 2x-3=5=\ \textgreater \ 2x=8=\ \textgreater \ \boxed{x=4}. \\ \\ Solutie:~\boxed{x=4}.$
