Factorise ;

x² + 7x+6

$\qquad\rule{120pt}{2pt}$

$\\ {\large{\textsf{\textbf{\underline{\underline{ Solution \: :}}}}}} \\$

$\\ \sf \implies \: {x}^{2} + 7x+6 \\$

$\\ \sf \implies \: {x}^{2} + 6x + x+6 \\$

$\\ \sf \implies \: x(x + 6) +1 (x+6) \\$

$\\ \sf \implies \: (x + 6) (x+1) \\$

$\\ \sf \implies \: x + 6= 0 \:\:\:\: and\:\:\:\: x+1=0 \\$

$\\ \sf \implies \: x= 0 -6\:\:\:\: and\:\:\:\: x=0-1 \\$

$\\ \sf \implies \: x= -6\:\:\:\: and\:\:\:\: x=-1 \\$

$\\\sf\implies\;{\underline{\boxed {\bf{ \:\:x=-6\:\: }}} }\red\bigstar \;\; \;\; \;{\underline{\boxed {\bf{ \:\:x=-1\:\: }}} }\red\bigstar \\$
