[tex]\mathsf{x^2+6x=40}\\\mathsf{SUBTRACT\ 40\ on\ your\ sides}\\\mathsf{x^2+6x-40=40-40}\\\mathsf{CANCEL\ out: 40-40\ because\ it\ gives\ you\ 0}\\\mathsf{New\ equation: x^2+6x-40=0}\\\mathsf{FACTO\ | OUT\ side\ of the\ equation}[/tex]
[tex]\mathsf{(x-4)=0}\\\mathsf{(x+10)=0}\\\mathsf{=(x-4)(x+10)=0}\\\mathsf{ANSWER\ those\ above\ and\ you\ will\ find\ your\ x-values}\\\\\\\boxed{\boxed{\mathsf{This\ your\ answer\ is: \boxed{\mathsf{\bf{x=4\ and\ x=}-10}}}}}\checkmark[/tex]
