Completing the squareis a method that is used for converting a quadratic expression of the form ax2+ bx + c to the vertex form a(x - h)2+ k. The most common application of completing the square is in solving a quadratic equation. This can be done by rearranging the expression obtained...
number, such as "1", and then the cell B1 enter the formula in accordance with the equation solving "= LOG (A1) + A1 ^ 2". oapdf.com 我们只需要先在A1单元格中随意输入一个数字,比如“1”,然后在B1单元格 按 照 所 求 解方 程 输 入 公 式“ =L OG(A1)+A1^2”。 oa...
These methods are factoring, the quadratic formula, and completing the square. Each different method produces the same answer, but some methods are much simpler to use than others. Although the simplest of the three listed methods, factoring has a few limitations and cannot always be used to ...
