sqrt(k^2-2k+1)-1=2k

k^{2} - 2 k + 1 - 1 = 2 k

k = 0

Solution steps

k^{2} - 2 k + 1 - 1 = 2 k

Remove square roots

k^{2} - 2 k + 1 = 4 k^{2} + 4 k + 1

Solve

k^{2} - 2 k + 1 = 4 k^{2} + 4 k + 1 : k = - 2, k = 0

k = - 2, k = 0

Verify Solutions:

k = - 2

False

, k = 0

True

The solution is

k = 0

20 - x = - x

G (x) = x^{2} - 81

\frac{x}{10} = 1

y, - y + 30 = y
