Solve equations by elimination
In this blog post, we will explore one method of Solving equations by elimination. Interested readers can find relevant materials to read Xie Huimin pointed out that the unexpected encounter with I was an important event accidentally caused by the solution of the root formula of the cubic equation . It may be strange that the appearance of complex numbers in history is not related to the solution of quadratic equations such as x2 + 1 = 0. Because when encountering a quadratic equation with a pair of conjugate complex roots, the general practice of mathematicians at that time was to ignore it, thinking that the equation had no solution, or that it was meaningless at all. However, this practice of abandoning it has encountered difficulties in solving the cubic equation. For example, solve x3-63x-162 = 0.
It often needs to be converted into area sum or area difference by means of cut and complement method, or by equal product transformation. Summary: as can be seen from the above examples, there are various areas of the shadow part of the circle, and there are also many ways to solve it. However, as long as the shadow in the thinking is removed through appropriate transformation and flexible processing according to the characteristics of the figure, it will certainly bring a bright future to the solution of the problem. Finally, I will improve the content of this part, using the characteristics of the coordinate system to solve the area of relevant graphics, and the specific graphics are proposed and solved by students themselves, so as to cultivate students' divergent thinking and feel the application of cut and fill here.
So I researched and solved the equations by myself. The general and simple form should be n equations containing n unknowns. The unknown coefficients form an n-order determinant, and the coefficient matrix In the two-dimensional case, increasing the modulus or angle of the vector can increase the volume of the polyhedron. So dissimilarity here is the core.
When doing big math problems, don't be too nervous. Just get all the basic scores, and you can get a good score. Therefore, when doing difficult problems, don't be afraid, first filter out the ideas, because math is scored step by step. As long as you take the steps, you can score. The second point is to pay attention to the standardization of answers.

This app is amazing! I've been using it for 2 years now and I love it so much! It's easy to use and you can also see how they solve it, this app made my high school life much, much easier. It doesn't have ads which is amazing too! I do miss the old version where it didn't need internet but it's still the same. Thank you!
I love this app so far! I was having trouble with pre-algebra because of the homeschooling, so I decided to look around and look which one most people said and it was the app so I wanted to give it a try. Every time I have had a question I have gone to this app and it is wonderful. I highly prefer it to anyone just having some struggles with math homework.
