\(5.\left(x-3\right)+\left(x-2\right).\left(5x-1\right)=5x^2\)
\(\Rightarrow5x-15+5x^2-x-10x+2=5x^2\)
\(\Rightarrow5x-15+5x^2-x-10x+2-5x^2=0\)
\(\Rightarrow-6x-13=0\)
\(\Rightarrow-6x=0+13\)
\(\Rightarrow-6x=13\)
\(\Rightarrow x=13:\left(-6\right)\)
\(\Rightarrow x=-\frac{13}{6}\)
Vậy \(x=-\frac{13}{6}.\)
Chúc bạn học tốt!
