Have you ever worked with variables? Algebra is a branch of mathematics that specifically deals with the idea of using variables to solve problems. What kinds of problems have you already solved using variables? Do you know any real-life applications for variables?Think about the numbers you encounter in the world around you. Do you understand what they really mean? Interactions at grocery stores, gas stations, and online shopping commonly involve numbers. These interactions can be better understood using algebra. Is there anything you don’t know involving numbers that you wish you better understood?

Answer:
Well, I think we all worked with variables, but don't realise about it, because when people see these terms ''variable'', ''algebra'', they freak out.
The reality is that variables are everywhere, they are all those stuff that can variate: weigh, highness, money, population, interests, and so on.
A common problem I solved using variables is measuring time. For example, when I'm going to school I tend to calculate the time of my way.

Answer:
The factors of x^2 + 16 are (x - 4i) and (x + 4i).
Step-by-step explanation:
That'd be x^2 + 16, not x2 + 16.
First, an easier example: x^2 - 16 factors into (x - 4)(x + 4).
Note how (-4)(4) = -16.
The corresponding factors of x^2 + 16 are (x - 4i) and (x + 4i).
We can check this result through multiplication: (x - 4i)(x + 4i) = x^2 - 4ix + 4ix - 16(-1), or x^2 + 16.

Answer:
x² + y² = 85
Step-by-step explanation:
Using the expansion
(x - y)² = x² + y² - 2xy , then
x² + y² - 2xy = (x - y)² ( add 2xy to both sides )
x² + y² = (x - y)² + 2xy ← substitute given values
= 9² + 2(2)
= 81 + 4
= 85
