Simplifying (2 + 5i)(7 + -1i) = 0 Multiply (2 + 5i) * (7 + -1i) (2(7 + -1i) + 5i * (7 + -1i)) = 0 ((7 * 2 + -1i * 2) + 5i * (7 + -1i)) = 0 ((14 + -2i) + 5i * (7 + -1i)) = 0 (14 + -2i + (7 * 5i + -1i * 5i)) = 0 (14 + -2i + (35i + -5i2)) = 0 Combine like terms: -2i + 35i = 33i (14 + 33i + -5i2) = 0 Solving 14 + 33i + -5i2 = 0 Solving for variable 'i'. Factor a trinomial. (7 + -1i)(2 + 5i) = 0Subproblem 1
Set the factor '(7 + -1i)' equal to zero and attempt to solve: Simplifying 7 + -1i = 0 Solving 7 + -1i = 0 Move all terms containing i to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -1i = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1i = 0 + -7 -1i = 0 + -7 Combine like terms: 0 + -7 = -7 -1i = -7 Divide each side by '-1'. i = 7 Simplifying i = 7Subproblem 2
Set the factor '(2 + 5i)' equal to zero and attempt to solve: Simplifying 2 + 5i = 0 Solving 2 + 5i = 0 Move all terms containing i to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + 5i = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 5i = 0 + -2 5i = 0 + -2 Combine like terms: 0 + -2 = -2 5i = -2 Divide each side by '5'. i = -0.4 Simplifying i = -0.4Solution
i = {7, -0.4}
