Simplifying (-7 + i)(9 + i) = 0 Multiply (-7 + i) * (9 + i) (-7(9 + i) + i(9 + i)) = 0 ((9 * -7 + i * -7) + i(9 + i)) = 0 ((-63 + -7i) + i(9 + i)) = 0 (-63 + -7i + (9 * i + i * i)) = 0 (-63 + -7i + (9i + i2)) = 0 Combine like terms: -7i + 9i = 2i (-63 + 2i + i2) = 0 Solving -63 + 2i + i2 = 0 Solving for variable 'i'. Factor a trinomial. (-9 + -1i)(7 + -1i) = 0Subproblem 1
Set the factor '(-9 + -1i)' equal to zero and attempt to solve: Simplifying -9 + -1i = 0 Solving -9 + -1i = 0 Move all terms containing i to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + -1i = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -1i = 0 + 9 -1i = 0 + 9 Combine like terms: 0 + 9 = 9 -1i = 9 Divide each side by '-1'. i = -9 Simplifying i = -9Subproblem 2
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 = 7Solution
i = {-9, 7}
