Question

Solve. (x – 6)^2 = 2

Answer 1

hint
(a-b)^2=a^2-2ab+b^2

Answer 2

Assuming you're solving for x, first try taking the square root of each side.

Answer 3

(x – 6)^2 = 2
x^2-12x+36=2
add -2 to both sides
x^2-12x+34=0

Answer 4

@Auxuris u made a mistake the third term is 6^2 not 2^2

Answer 5

in case it wasn't clear, okay basically you have the identity rule of

(a^2-2ab+b^2)=(a+b)2
its the second factorisation identity, you've gotta memorise it^^
