3x^2+2sqrt(5x)-5=0

3 x^{2} + 2 5 x - 5 = 0

x \approx 0.66891 \dots

Solution steps

3 x^{2} + 2 5 x - 5 = 0

Remove square roots

20 x = 9 x^{4} - 30 x^{2} + 25

Solve

20 x = 9 x^{4} - 30 x^{2} + 25 : x \approx 0.66891 \dots, x \approx 1.93382 \dots

x \approx 0.66891 \dots, x \approx 1.93382 \dots

Verify Solutions:

x \approx 0.66891 \dots

True

, x \approx 1.93382 \dots

False

The solution is

x \approx 0.66891 \dots

c^{7.2} = 36

x, x^{\frac{1}{2}} + y^{\frac{1}{2}} = a^{\frac{1}{2}}

3^{3} x + 5 = 26

x^{2} - 2 2 x - 23 = 0

y^{2} = \frac{5}{2 \cdot lo g _{2} ( 16 ) + 5.4}
