Explanation: Use "FOIL" technique: (First, Outer, Inner, and Last Terms);
then, combine the "like terms", to simplify.
__________________________________________
(5x+4)(9x+9) = 45x² + 45x + 36x + 35 = 45x² + 81x + 36 .

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
z₁ / z₂ = (4 - j) / (2 + 5j)
= [ (4 - j) / (2 + 5j)] * [ (2 - 5j) / (2 - 5j)] = 0.448 + 0.62j = 0.766∠54.2°
The value of z₁ / z₂ = (4 - j) / (2 + 5j) in euler form given as
