Question

The square root of x minus two plus 8 equals x

Answer 1

Step-by-step explanation:

$\sqrt{x - 2 + 8} = \sqrt{x + 6} = x$

${( \sqrt{x + 6} })^{2} = {x}^{2}$

$x + 6 = {x}^{2}$

${x}^{2} - x - 6 = 0$

$(x - 3)(x + 2) = 0$

x = 3 or x = -2 we dont use the (-2) because we have a sqrt

So x =3
