1.Expand and simplify second-degree polynomial expressions.
2.Factor polynomial expressions involving common factors,trinomials and different of squares.
3.Solve quadratic equations that have real roots.
4.Solve systerms of two linear equations involving two variables by graphing.Solve systerms of two linear equations involving two variables by using the algebraic method of substitution or elimination.
5.Solve problems involving the slope length,and midpoint of a line segment.
6.Determine the radius of a circle with center(0.0)given its equation.
8.Understand the roles of a,h,and k in y=a(x-h)2 to identify the transformations.
9.Sketch by hand,graphs by applying transformations.
特别是第6!还有第2 和第4 第8!
还有几个单词要求解答,
linear relations linear equation
是不是线性关系 和 线性方程 的意思呢?
还有 a "balance" modle ,我不理解了.
倘若可以帮我解决问题的话，我一定加很多很多的分给你们1！
