Solve (x^2)/3 (3x-1)/5 =-2

Evaluate

\frac{x ^{2}}{3} \times \frac{3 x - 1}{5} = - 2

Multiply the terms

More Steps

\frac{x ^{2} ( 3 x - 1 )}{15} = - 2

Cross multiply

x^{2} (3 x - 1) = 15 (- 2)

Simplify the equation

x^{2} (3 x - 1) = - 30

Expand the expression

More Steps

3 x^{3} - x^{2} = - 30

Move the expression to the left side

3 x^{3} - x^{2} - (- 30) = 0

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

3 x^{3} - x^{2} + 30 = 0

Solution

x \approx - 2.048857
