2 x + 1 + x - 1 = 4

x = 2 (23 - 429)

Decimal Notation

x = 2.91868 \dots

Solution steps

2 x + 1 + x - 1 = 4

Remove square roots

x^{2} - 28 x + 196 = 64 x - 64

Solve

x^{2} - 28 x + 196 = 64 x - 64 : x = 2 (23 + 429), x = 2 (23 - 429)

x = 2 (23 + 429), x = 2 (23 - 429)

Verify Solutions:

x = 2 (23 + 429)

False

, x = 2 (23 - 429)

True

The solution is

x = 2 (23 - 429)

5 = 10 (0.55)^{0.2} K^{0.4}

3 = 3 x^{3} + 2 x^{2} + 3 x + 1

2 x + 1 + x - 1 = 1

2 = x^{\frac{5}{3}}

x^{2} + 3 x - x^{2} + 3 x - 1 - 7 = 0
