Answer 1

We have,

$\[ \begin{array}{l} \\ \rm\implies x^{2}+x-20=0 \\\\ \rm\implies x^{2}+5 x-4 x-20=0 \\\\ \rm\implies x(x+5)-4(x+5)=0 \\ \\ \rm\implies(x+5)(x-4)=0 \\\\ \rm\implies x+5=0 \text { or } x-4=0 \\\\ \color{blue}{\boxed {\rm\implies x=-5 \text { or } x=4 }}\end{array} \]$

Answer is x=4, x= -5
