Question

(x-3)(x+2)=14                     .............

Answer 1

[tex](x-3)(x+2)=14 \\ ~~~~~1~~~~~~~14 \\ ~~~~~14~~~~~~~1 \\ ~~~~~2~~~~~~~~7 \\ ~~~~~7~~~~~~~~2 \\ x-3 \in\{1,14,2,7\}|+3 \\ x \in \{4,17,5,10\}(1) \\ x+2 \in \{14,1,7,2\}|-2 \\ x \in \{12,-1,5,0\}(2) \\ Din~(1)~si~(2) \Longrightarrow \boxed{x=5}[/tex]
