Question

Solve the quadratic equation.


(x - 5)2 = 9

Answer 1

is (x-5) raised to the 2nd?

Answer 2

Take the square root of (x-5)^2 and the square root of 9.
This results in x-5=3
Add 5 to both sides.
x=8

Answer 3

\(x-5=\sqrt{9}\\x=-3+5 \ or\ x=3+5\)
remember that when calculating for the square root, it is either "positive" or "negative"
