Answer 2

$\large\bf\color{navy}{To~factorise~:}$

$\large\tt{x^{2}+13x+40=0}$

$\large\bf\color{navy}{Here,~S=13,~~P=40~~(8,~5)}$

$\large\tt{→x^{2}+5x+8x+40=0}$

$\large\tt{→[x(x+5)~]+[8(x+5)~]=0}$

$\large\tt{→(x+5)(x+8)=0}$

$\large\tt{→x+5=0~~or~~x+8=0}$

$\large\tt{→x=-5~~~or~~~x=-8}$

$\large\bf{~~\therefore~The~roots~are:~{\tt{-5}}~and{\tt{-8}}}$
