4x^3-3x^{2.5}-3x+9=15

4 x^{3} - 3 x^{2.5} - 3 x + 9 = 15

x \approx 1.85976 \dots

Solution steps

4 x^{3} - 3 x^{2.5} - 3 x + 9 = 15

Remove roots

9 x^{5} = (- 4 x^{3} + 3 x + 6)^{2}

Solve

9 x^{5} = (- 4 x^{3} + 3 x + 6)^{2} : x \approx 1.10830 \dots, x \approx 1.85976 \dots

x \approx 1.10830 \dots, x \approx 1.85976 \dots

Verify Solutions:

x \approx 1.10830 \dots

False

, x \approx 1.85976 \dots

True

The solution is

x \approx 1.85976 \dots

x + x^{\frac{1}{2}} = 20

(x^{2} - 16) \cdot 3 - x = 0

x + a + x = \frac{( 3 a )}{( a + x )}

v, 5 w = \frac{( ( v + 2 ) ^{\frac{1}{2}} )}{3}

x, z = x y + y \cdot x^{2} - a^{2} + b
