Simplifying z2 + -1z(k + 4) + 4k = 0 Reorder the terms: z2 + -1z(4 + k) + 4k = 0 z2 + (4 * -1z + k * -1z) + 4k = 0 Reorder the terms: z2 + (-1kz + -4z) + 4k = 0 z2 + (-1kz + -4z) + 4k = 0 Reorder the terms: 4k + -1kz + -4z + z2 = 0 Solving 4k + -1kz + -4z + z2 = 0 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '4z' to each side of the equation. 4k + -1kz + -4z + 4z + z2 = 0 + 4z Combine like terms: -4z + 4z = 0 4k + -1kz + 0 + z2 = 0 + 4z 4k + -1kz + z2 = 0 + 4z Remove the zero: 4k + -1kz + z2 = 4z Add '-1z2' to each side of the equation. 4k + -1kz + z2 + -1z2 = 4z + -1z2 Combine like terms: z2 + -1z2 = 0 4k + -1kz + 0 = 4z + -1z2 4k + -1kz = 4z + -1z2 Reorder the terms: 4k + -1kz + -4z + z2 = 4z + -4z + -1z2 + z2 Combine like terms: 4z + -4z = 0 4k + -1kz + -4z + z2 = 0 + -1z2 + z2 4k + -1kz + -4z + z2 = -1z2 + z2 Combine like terms: -1z2 + z2 = 0 4k + -1kz + -4z + z2 = 0 The solution to this equation could not be determined.
