(x - 2) ^2 - 3=12 solve by square roots

X = 2+ sqrt(15)

X = 2- sqrt(15)

Step-by-step explanation:

(X - 2) ^2 - 3=12

add 3 to each side

(X - 2) ^2 - 3+3=12+3

(X - 2) ^2 =15

take the square root of each side

sqrt((X - 2) ^2) =+-sqrt(15)

(X-2) = +- sqrt(15)

add 2 to each side

X-2+2 = 2+- sqrt(15)

X = 2+- sqrt(15)

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

the answer is 2/54
