12x-7 times the square root of x + 1=0
%2812x-7%29%28sqrt%28x%2B1%29%29=0
%2812x-7%29=0 add 7 to both sides
12x=7 divide both sides by 12
x=7%2F12--------------------one answer
and
sqrt%28x%2B1%29=0 square both sides

x%2B1=0 subtract 1 from both sides
x=-1----------------------------------the other answer
CK
%2812%287%2F12%29-7%29%28sqrt%28%287%2F12%29%2B1%29%29=0
0=0
and
%2812%28-1%29-7%29%28sqrt%280%29%29=0
0=0

Hope this helps------ptaylor
