To solve the equation \( 4 m^{3}+4 m^{2}-8 m=0 \), let's first factor out the greatest common factor, which is \( 4m \): \[ 4m(m^{2} + m - 2) = 0 \] Now, we can set each factor equal to zero. The first factor gives us: \[ 4m = 0 \implies m = 0 \] For the second factor, we solve the quadratic equation \( m^{2} + m - 2 = 0 \). We can use the factoring method here: \[ m^{2} + m - 2 = (m + 2)(m - 1) = 0 \] Setting each factor to zero gives us: \[ m + 2 = 0 \implies m = -2 \] \[ m - 1 = 0 \implies m = 1 \] So, the solutions to the equation \( 4 m^{3}+4 m^{2}-8 m=0 \) are: \[ m = 0, \, m = -2, \, \text{and} \, m = 1 \]
