Here \: is \: the \: answer \: of \: your \: question

1) x² - 4x + 3

x² - 3x - x + 3

\textbf{x (x - 3) - 1 (x - 3)}

\textbf{(x - 3) (x - 1)}

\textbf{x = + 3, + 1}
___________________________________

2) x² - 6x - 7

x² - 7x + x - 7

\textbf{x (x - 7) + 1 (x - 7)}

\textbf{(x - 7) (x + 1)}

\textbf{x = + 7, - 1}
___________________________________

3) y² - 21y - 72

y² - 24y + 3y - 72

\textbf{y (y - 24) + 3 (y - 24)}

\textbf{(y - 24) (y + 3)}

\textbf{y = + 24, - 3}
___________________________________

4) x² - 18x + 65

x² - 13x - 5x + 65

\textbf{x (x - 13) - 5 (x - 13)}

\textbf{(x - 13) (x - 5)}

\textbf{x = + 13, + 5}
