Question

Solve. x^2 – 4x = 14

Answer 1

lol

Answer 2

these are the answers given to choose from

2 ± radical 14

2 ± 2 radical 3

2 ± 3 radical 2

2 ± radical 10

Answer 3

Possible intermediate steps:
x^2-4 x = 14
Add 4 to both sides:
x^2-4 x+4 = 18
Factor the left hand side:
(x-2)^2 = 18
Take the square root of both sides:
abs(x-2) = 3 sqrt(2)
Eliminate the absolute value:
x-2 = -3 sqrt(2) or x-2 = 3 sqrt(2)
Add 2 to both sides:
x = 2-3 sqrt(2) or x-2 = 3 sqrt(2)
Add 2 to both sides:
x = 2-3 sqrt(2) or x = 2+3 sqrt(2

Answer 4

the second
