Question

(x-3) (x+3)= (x-5)^2

Answer 1

=>x^2-10x+25=x^2-9

=>-10x=-9-25=-34

=>x=17/5

Answer 2

\(\left(x-3\right)\left(x+3\right)=\left(x-5\right)^2\)

\(\Leftrightarrow x^2-3^2=x^2-10x+25\)

\(\Leftrightarrow x^2-x^2+10x=25+9\)

\(\Leftrightarrow10x=34\)

\(\Leftrightarrow x=\dfrac{34}{10}\)

\(\Leftrightarrow x=\dfrac{17}{5}\)
