Question

I need help with this problem. Any help is needed.

(x-2)²=17

Answer 1

Step-by-step explanation:

(x-2)^2=17

here

, we use the formula

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

applying this formula

x^2-4x+ 4=17

x^2-2x-2x+4 =17

x(x-2)-2(x-2)=17

(x-2)(x-2) = 17

x-2 = 17

x = 17+2

= 19

so the answer is X equal to 19
