sqrt(12+4x)+sqrt(2x+10)=2

12 + 4 x + 2 x + 10 = 2

x = - 3

Solution steps

12 + 4 x + 2 x + 10 = 2

Remove square roots

4 x^{2} - 8 x + 4 = 32 x + 160

Solve

4 x^{2} - 8 x + 4 = 32 x + 160 : x = 13, x = - 3

x = 13, x = - 3

Verify Solutions:

x = 13

False

, x = - 3

True

The solution is

x = - 3

x^{4} = x^{2}

x - 6 = x - 3

3 x - 2 + x - 1 - 3 = 0

0 = 7 x + 36 - 5 x + 16 - 2

x + 5 - 3 = x
