You will apply them when solving quadratic equations in which the quadratic expression cannot be factorised.
Quadratic equations can be used in many real world situations, particularly in the fields of business, engineering, and science. They can be used to help predict how much a business will earn or lose and thus allow that business to figure out how to maximize its profit. Kayakers also use these equations to determinate their speed while traveling up or down a river.
Many real life physics problems are parabolic in nature. Parabolas can be shown as a quadratic equation. If you have two variables then usually you can use the equation to find the best solution to a problem. Also, it is a beginning in the world of mathematical optimization. Some equations use more than two variables and require the technique used to solve quadratics to solve them. I just ran an optimization of 128 variables. To understand the parameters I needed to set I had to understand quadratics.
You can use a graph to solve systems of equations by plotting the two equations to see where they intersect

School is part of real life... if you are using equations in school that is real.
no
That is used mainly to solve equations.
There are no 'equations' on a number line. There are only numbers, such as 1, 2, 3...and so on. And they relate to life because you use them in counting. And you use that to count money, people, fingers, etc.
well, if you know all the formulating equations it will make you better at regular equations and regular equations can be used in everyday life

The additive inverse is used to solve equations; equations, in turn, are used to model many real-world situations.
it help us in this life because we can be able to use signs and alphabet to represent data

Ir is in some people's real life. Example: millions of students that want to pass algebra.
Multi-step equations can be used in various real-life situations. For example, when planning a budget, multi-step equations can be used to calculate monthly expenses and income. They can also be used in engineering and physics to solve complex problems involving multiple variables and equations. Additionally, in chemistry, multi-step equations are used to balance chemical reactions and determine the quantities of reactants and products.
If you work in engineering and science, you'll need equations all the time in your "real life" (i.e., at work), to solve all sorts of problems. Apart from that, most people don't use equations much - not so much because they can't be useful, but because "regular" people usually don't like to bother themselves with remembering algebra.
