How to determine the mathematical distance problem of pipe synthesis and the solution of quadratic equation with one variable
When solving a quadratic equation with one variable, don't rush to find the general formula, but observe its characteristics first. The order of the four solutions is: ① direct Kaiping method, ② factorization method (including cross multiplication, raising common factor method and formula factorization method), ③ collocation method and ④ formula method.
