Question 303299
I assume the square root term encloses the entire left hand side??
{{{sqrt(x^2+9x+14)=x+4}}}
{{{x^2+9x+14=(x+4)^2}}}
{{{x^2+9x+14=x^2+8x+16}}}
{{{highlight_green(x=2)}}}
.

Verify the solution.
{{{sqrt(x^2+9x+14)=x+4}}}
{{{sqrt(2^2+9(2)+14)=2+4}}}
{{{sqrt(4+18+14)=6}}}
{{{sqrt(36)=6}}}
{{{6=6}}}
True, it's a good solution.
