Question 928907


{{{5(x+7)^2=5}}}

{{{(x+7)^2=5/5}}}

{{{(x+7)^2=1}}}

{{{x^2+14x+7^2=1}}}

{{{x^2+14x+49-1=0}}}

{{{x^2+14x+48=0}}}

{{{x^2+8x+6x+48=0}}}

{{{(x^2+8x)+(6x+48)=0}}}

{{{x(x+8)+6(x+8)=0}}}

{{{(x+6)(x+8) = 0}}}

solutions:

if {{{x+6 = 0}}}=> {{{x=-6}}}

if {{{x+8 = 0}}}=> {{{x=-8}}}
