Simplifying sqrt(2k + 4) + -1sqrt(-1 + -1k) = -1 Reorder the terms: qrst(4 + 2k) + -1sqrt(-1 + -1k) = -1 (4 * qrst + 2k * qrst) + -1sqrt(-1 + -1k) = -1 Reorder the terms: (2kqrst + 4qrst) + -1sqrt(-1 + -1k) = -1 (2kqrst + 4qrst) + -1sqrt(-1 + -1k) = -1 2kqrst + 4qrst + (-1 * -1qrst + -1k * -1qrst) = -1 Reorder the terms: 2kqrst + 4qrst + (1kqrst + 1qrst) = -1 2kqrst + 4qrst + (1kqrst + 1qrst) = -1 Reorder the terms: 2kqrst + 1kqrst + 4qrst + 1qrst = -1 Combine like terms: 2kqrst + 1kqrst = 3kqrst 3kqrst + 4qrst + 1qrst = -1 Combine like terms: 4qrst + 1qrst = 5qrst 3kqrst + 5qrst = -1 Solving 3kqrst + 5qrst = -1 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-5qrst' to each side of the equation. 3kqrst + 5qrst + -5qrst = -1 + -5qrst Combine like terms: 5qrst + -5qrst = 0 3kqrst + 0 = -1 + -5qrst 3kqrst = -1 + -5qrst Divide each side by '3qrst'. k = -0.3333333333q-1r-1s-1t-1 + -1.666666667 Simplifying k = -0.3333333333q-1r-1s-1t-1 + -1.666666667 Reorder the terms: k = -1.666666667 + -0.3333333333q-1r-1s-1t-1
