Solution is y = 4e² - 5 /2+e²
By applying log laws we can reach the following:
ln(2y+5/...

y = 5x - 5

x*ln|x| - x

The idea here is to explain to the student that i^2=-1, and to expand and simplify the brackets in question just like they would with simple algebra. Therefore:
(5+3i)*(3+5i)=15+25i+9i+15i^2=15+34i-1...

When expanding quadratics, the ‘smiley face’ method is the easiest one to follow. Do each term individually. The lines you draw between the terms will resemble a smiley face. Ensure that there are 2 lines...
