Solution for (5+i)(8+I)= equation:


Simplifying
(5 + i)(8 + I) = 0

Multiply (5 + i) * (8 + I)
(5(8 + I) + i(8 + I)) = 0
((8 * 5 + I * 5) + i(8 + I)) = 0
((40 + 5I) + i(8 + I)) = 0
(40 + 5I + (8 * i + I * i)) = 0
(40 + 5I + (8i + iI)) = 0
(40 + 5I + 8i + iI) = 0

Solving
40 + 5I + 8i + iI = 0

Solving for variable 'I'.

Move all terms containing I to the left, all other terms to the right.

Add '-40' to each side of the equation.
40 + 5I + 8i + -40 + iI = 0 + -40
