It helps to think of a simpler problem. Let's say mpg is 20 and 10% higher on a smooth road.

How many miles will you get with one gallon on a regular road?

How many more miles will you get on a smooth road? 10% more, right? How much is that?

OK - so you've now solved a simpler problem. Use the exact some process to solve your, more complicated, problem.

Answer:

$(x + (3+5i))^2 = x^2 + 6x + (10x+30)i - 16$

Step-by-step explanation:

Complex numbers identity:

The complex numbers identity is:

$i^2 = -1$

Square of the sum:

$(x + y)^2 = x^2 + 2xy + y^2$

In this question:

$(x + (3+5i))^2$

$x^2 + 2x(3+5i) + (3+5i)^2$

$x^2 + 6x + 10xi + 9 + 30i + 25i^2$

$x^2 + 6x + 9 + (10x+30)i - 25$

$x^2 + 6x + (10x+30)i - 16$

$(x + (3+5i))^2 = x^2 + 6x + (10x+30)i - 16$
