Question 696109
You wrote {{{(5x+2^2)=53}}}
{{{(5x+2^2)=53}}}-->{{{5x+2^2=53}}}-->{{{5x+4=53}}}-->{{{5x=53-4}}}-->{{{5x=49}}}-->{{{x=49/5}}}
 
You probably meant to type {{{(5x+2)^2=53}}}
{{{(5x+2)^2=53}}}-->{{{5x+2=sqrt(53)}}} OR {{{5x+2=-sqrt(53)}}}
{{{5x+2=sqrt(53)}}}-->{{{5x=-2+sqrt(53)}}}-->{{{x=(-2+sqrt(53))/5}}}
{{{5x+2=-sqrt(53)}}}-->{{{5x=-2-sqrt(53)}}}-->{{{x=(-2-sqrt(53))/5}}}
 
We like to write both solutions in one equation as
{{{highlight(x=(-2 +- sqrt(53))/5)}}}
