3z^2-2sqrt(z)-1=0

3 z^{2} - 2 z - 1 = 0

z = 1

Solution steps

3 z^{2} - 2 z - 1 = 0

Remove square roots

4 z = 9 z^{4} - 6 z^{2} + 1

Solve

4 z = 9 z^{4} - 6 z^{2} + 1 : z = 1, z \approx 0.19580 \dots

z = 1, z \approx 0.19580 \dots

Verify Solutions:

z = 1

True

, z \approx 0.19580 \dots

False

The solution is

z = 1

0 = \frac{h}{70}

5 + 2 x + 1 = 10

10 x - 1 = 7

5 x + 1 = 4 x - 5

x, y = x - 9
