Answer:

x = 3 ± √6.

or 0.55, 5.45 to the nearest hundredth.

Explanation:

(x−3)^2+2=8

(x - 3)^2 = 8 - 2 = 6

(x - 3)^2 = 6

Taking square roots of both sides:

x - 3 = +/- √6

x = 3 ± √6.

Answer:

Given quadratic equation:-


\rm{(x - 3) 2 + 2 = 8}

Simplifying the given equation:-

1) Simplify both sides of the equation.


\rm{x^(2) - 6x + 11 = 8}

2) Subtract (8) from both sides, we get:


\rm{x^(2) - 6x + 11 - 8 = 8 - 8}


\rm{x^(2) - 6x + 3 = 0}

3) In the equation: (a = 1), (b = -6), (c = 3):


\rm{1x^(2) + - 6x + 3 = 0}

4) Use quadratic formula:


\rm{x = \frac{-b \pm \sqrt{b^(2) - 4ac}}{2a}}


\rm{x = \frac{-(-6) \pm\sqrt{(-6)^(2) - 4 (1) (3)}}{2 * 1}}


\rm{x = (6 \pm √(4))/(2)}


{\boxed{\rm{x = 3 \pm √(6)}}}
