Simplifying 2i(7 + 5i) = 0 (7 * 2i + 5i * 2i) = 0 (14i + 10i2) = 0 Solving 14i + 10i2 = 0 Solving for variable 'i'. Factor out the Greatest Common Factor (GCF), '2i'. 2i(7 + 5i) = 0 Ignore the factor 2.Subproblem 1
Set the factor 'i' equal to zero and attempt to solve: Simplifying i = 0 Solving i = 0 Move all terms containing i to the left, all other terms to the right. Simplifying i = 0Subproblem 2
Set the factor '(7 + 5i)' equal to zero and attempt to solve: Simplifying 7 + 5i = 0 Solving 7 + 5i = 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 + 5i = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 5i = 0 + -7 5i = 0 + -7 Combine like terms: 0 + -7 = -7 5i = -7 Divide each side by '5'. i = -1.4 Simplifying i = -1.4Solution
i = {0, -1.4}
