sqrt(2x+21)-sqrt(2x+12)=1

2 x + 21 - 2 x + 12 = 1

x = 2

Solution steps

2 x + 21 - 2 x + 12 = 1

Remove square roots

64 = 8 x + 48

Solve

64 = 8 x + 48 : x = 2

x = 2

Verify Solutions:

x = 2

True

The solution is

x = 2

(11 - 6)^{2} + x = 32

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

x - 8 = 2

2 x + 6 + 4 = x + 3

\frac{x ^{2} + 2 x + 1}{2} = 0
