Answer:
Step-by-step explanation:
Foil the equation!
1. You see that is to the second power so it means this 
2. Then you use the Foil method. First, Outside, Inside, and Last.
3. Combined like terms
4. Answer!
A tip you can use to avoid Foil is this mental math trick: (Keep in mind this only works if the polynomial is being squared.)
1. Multiply the first number by itself = 
2. Add the first number by itself = 
3. Multiply the last number by itself = 
4. Combined to form your answer =
NOTE: This is the same thing as a foil but it uses mental math so it takes less time!

The required coordinate of A will be at (-4, 0)
When a point bisects a line, it cuts the line into two equal parts and the point on that line is known as its midpoint. The expression for calculating the midpoint of a line is expressed as;
![M(X, Y)= [{ \frac{x_2+x_1}{2} , \frac{y_2+y_1}{2} ]](https://tex.z-dn.net/?f=M%28X%2C%20Y%29%3D%20%5B%7B%20%5Cfrac%7Bx_2%2Bx_1%7D%7B2%7D%20%2C%20%5Cfrac%7By_2%2By_1%7D%7B2%7D%20%5D)
where:
From the question, we are given the following coordinate points
Get x₂;
Get y₂;
Hence the coordinate of A will be (-4, 0)

Step-by-step Answer:
What is the solution to the system of equations?
y = –3x – 2 ..............(1)
5x + 2y = 15..............(2)
Substitute (1) in (2) to give
5x + 2(-3x-2) = 15
5x-6x-4 = 15
-x-4=15
solve for x:
-4-15 = x
x=-19
Now substitute x=-19 into equation (1)
y = -3x-2 = 57-2 = 55
Therefore the solution is (-19, 55)
