$\red {\underline{\underline {Answer:}}}$

3 and 5.

$\red {\underline{\underline {Step-by-step\: explanation:}}}$

${x}^{2} - 8x + 15 = 0 \\ or, \: {x}^{2} - 3x - 5x + 15 = 0 \\ or, \: x(x - 3) - 5(x - 3) = 0 \\ or, \: (x - 3)(x - 5) = 0 \\ \\ either,\: x - 3 = 0 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: ∴ \: x = 3 \\ \\ or, \: x - 5 = 0 \\ \: \: \: \: ∴x = 5$
