Solve k^256 = -15k

Evaluate

k^{2} \times 56 = - 15 k

Use the commutative property to reorder the terms

56 k^{2} = - 15 k

Move the expression to the left side

56 k^{2} + 15 k = 0

Factor the expression

More Steps

k (56 k + 15) = 0

When the product of factors equals 0,at least one factor is 0

k = 0 56 k + 15 = 0

Solve the equation for k

More Steps

k = 0 k = - \frac{15}{56}

Solution

k_{1} = - \frac{15}{56}, k_{2} = 0

Alternative Form

k_{1} = - 0.267 \dot{8} 5714 \dot{2}, k_{2} = 0
