Solve 2w^2-7w^3 - ScanMath

Evaluate

2 w^{2} - 7 w^{3}

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

2 w^{2} - 7 w^{3} = 0

Factor the expression

w^{2} (2 - 7 w) = 0

Separate the equation into 2 possible cases

w^{2} = 0 2 - 7 w = 0

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

w = 0 2 - 7 w = 0

Solve the equation

More Steps

w = 0 w = \frac{2}{7}

Solution

w_{1} = 0, w_{2} = \frac{2}{7}

Alternative Form

w_{1} = 0, w_{2} = 0. \dot{2} 8571 \dot{4}
