Question

Completing the Square of x²=2x+33 ?

Answer 1

x^2 = 2 x+33
Subtract (2 x+33) from both sides:
x^2-2 x-33 = 0
Add 33 to both sides:
x^2-2 x = 33
Add 1 to both sides:
x^2-2 x+1 = 34
Factor the left hand side:
(x-1)^2 = 34
Take the square root of both sides:
sqrt(x-1) = sqrt(34)
Eliminate the absolute value:
x-1 = -sqrt(34) or x-1 = sqrt(34)
Add 1 to both sides:
x = 1-sqrt(34) or x-1 = sqrt(34)
Add 1 to both sides:
x = 1-sqrt(34) or x = 1+sqrt(34)

Answer 3

Dashing!

Answer 4

yep

Answer 5

so x = 1-sqrt(34) or x = 1+sqrt(34) is the final answer ?
