sqrt(x^2+5x+1)+1=2x

x^{2} + 5 x + 1 + 1 = 2 x

x = 3

Solution steps

x^{2} + 5 x + 1 + 1 = 2 x

Remove square roots

x^{2} + 5 x + 1 = 4 x^{2} - 4 x + 1

Solve

x^{2} + 5 x + 1 = 4 x^{2} - 4 x + 1 : x = 0, x = 3

x = 0, x = 3

Verify Solutions:

x = 0

False

, x = 3

True

The solution is

x = 3

x + 6 - 4 = 0

5 x - 16 = 7

(x + 3)^{\frac{1}{3}} = - 2

3 = 2^{2} + x^{2}

0 = x + x - 6
