Solve 4(2x 1)=5x^3x 9

Evaluate

4 (2 x \times 1) = 5 x^{3} \times x \times 9

Remove the parentheses

4 \times 2 x \times 1 = 5 x^{3} \times x \times 9

Multiply the terms

More Steps

8 x = 5 x^{3} \times x \times 9

Multiply

More Steps

8 x = 45 x^{4}

Add or subtract both sides

8 x - 45 x^{4} = 0

Factor the expression

x (8 - 45 x^{3}) = 0

Separate the equation into 2 possible cases

x = 0 8 - 45 x^{3} = 0

Solve the equation

More Steps

x = 0 x = \frac{2 3 75}{15}

Solution

x_{1} = 0, x_{2} = \frac{2 3 75}{15}

Alternative Form

x_{1} = 0, x_{2} \approx 0.562288
