Question 326988
<pre><b>
{{{(y+6)^2-75=0}}}

Get the squared term {{{(y+6)^2}}} by itself on the left side
by adding 75 to both sides

{{{(y+6)^2=75}}}

Take non-negative square roots of both sides

{{{sqrt((y+6)^2)= sqrt(75)}}}

{{{abs(y+6)=sqrt(25*3)}}}

{{{abs(y+6)=sqrt(25)*sqrt(3)}}}

{{{abs(y+6)=5*sqrt(3)}}}

{{{matrix(2,6,

y+6=5sqrt(3),"","","","",y+6=-5sqrt(3),
y=5sqrt(3)-6,"","","","",y=-5sqrt(3)-6)}}}
