step-by-step explanation:
we need to solve for 'x' the following equation:![\sqrt{(x+6)} - 4 = x](/tex.php?f=\sqrt{(x+6)} - 4 = x)
we have that:
⇒
⇒ ![x^{2} + 7x + 10 = 0](/tex.php?f=x^{2} + 7x + 10 = 0)
factorizing, we get that:
then, the solutions are:
or ![x=-5](/tex.php?f=x=-5)
nothing extraneous has been found!
