$\mathcal\purple{✰Explanation:-}$

$\color{orange} {\mid{\fbox{\sf{✰Given}}\mid}}$

${➟p(X)=X^2-4x+5}$

________________________

$\color{cyan} {\mid{\fbox{\sf{✰p(-1)}}\mid}}$

${➟p(-1)= (-1)^2-4(-1)+5}$

$\text{➟p(-1)= 1+4+5}$

$\text{➟p(-1)= 10}$ ---------->①

________________________

$\color{pink} {\mid{\fbox{\sf{✰p(-2)}}\mid}}$

${➟p(-2)= (-2)^2-4(-2)+5}$

$\text{➟p(-2)= 4+8+5}$

$\text{➟p(-2)= 17}$ ---------->②

________________________

$\color{magenta} {\mid{\fbox{\sf{✰p(-3)}}\mid}}$

${➟p(-3)= (-3)^2-4(-3)+5}$

$\text{➟p(-3)= 9+12+5}$

$\text{➟p(-3)= 26}$ ---------->③

________________________

✰Adding equations ①,②&③ we get,

$\text{➟p(-1)+p(-2)+p(-3)}$

$\text{➟10+17+26}$

${✰Which\: gives\: 53\: as\: the\: answer}$
