sqrt(6x+40)-sqrt(2x+28)=2

6 x + 40 - 2 x + 28 = 2

x = 4

Solution steps

6 x + 40 - 2 x + 28 = 2

Remove square roots

16 x^{2} + 64 x + 64 = 32 x + 448

Solve

16 x^{2} + 64 x + 64 = 32 x + 448 : x = 4, x = - 6

x = 4, x = - 6

Verify Solutions:

x = 4

True

, x = - 6

False

The solution is

x = 4

n + 4 + n - 1 = 5

2 x - 3 = x

(x^{2} + 24)^{\frac{1}{2}} = 7

x + 4 + x^{2} - 4 = 0

27 - 6 x - x = 0
