sqrt(x+1)=x^3-1

x + 1 = x^{3} - 1

x \approx 1.36396 \dots

Solution steps

x + 1 = x^{3} - 1

Square both sides:

x + 1 = x^{6} - 2 x^{3} + 1

x + 1 = x^{6} - 2 x^{3} + 1

Solve

x + 1 = x^{6} - 2 x^{3} + 1 : x = 0, x \approx 1.36396 \dots

x = 0, x \approx 1.36396 \dots

Verify Solutions:

x = 0

False

, x \approx 1.36396 \dots

True

The solution is

x \approx 1.36396 \dots

12 + 1 - 4 x = 15

x, x + y + 2 x y = 36

5.12 = 3.3 x^{1.7}

4 + x = 0

- 3 = - 4 + - 2 - x
