Solve 4x^4(9x^3 - 5)

Evaluate

4 x^{4} (9 x^{3} - 5)

To find the roots of the expression,set the expression equal to 0

4 x^{4} (9 x^{3} - 5) = 0

Elimination the left coefficient

x^{4} (9 x^{3} - 5) = 0

Separate the equation into 2 possible cases

x^{4} = 0 9 x^{3} - 5 = 0

The only way a power can be 0 is when the base equals 0

x = 0 9 x^{3} - 5 = 0

Solve the equation

More Steps

x = 0 x = \frac{3 15}{3}

Solution

x_{1} = 0, x_{2} = \frac{3 15}{3}

Alternative Form

x_{1} = 0, x_{2} \approx 0.822071
