Solving inequalities is very like solving equations ... you do most of the same things.When we solve inequalities we try to find interval(s), such as the ones marked "<0" or ">0"These are the steps:find "points of interest": the "=0" points (roots), and "vertical asymptotes" ...
√x2=52x2=52 化简方程的两边。 点击获取更多步骤... 使用axn=axn,将x重写成x12。 (x12)2=52 化简(x12)2。 将(x12)2中的指数相乘。 运用幂法则并将指数相乘,(am)n=amn。 x12⋅2=52 约去2的公因数。 x12⋅2=52 x1=52 x1=52 x1=52 ...
(x-4) 3. factor x+9=0 x-4=0 4. solve each for x=-9 x=4 zero Solving Rational Equations Cross Products You try: -12 = x-14 x 4 1. Cross multiply 2. Distribute 3. Factor 4. Set to zero if quadratic 5. Solve each set of parentheses. -12(4) = x(x-14) -48 = x 2...
While adding and subtracting rational expressions can be a royal pain, solving rational equations is generally simpler, even if rational expressions are added within those equations. (Note that I'm not saying that solving rational equations is "simple"; I'm only saying that it's simpler.) This...

An important step in solving rational equations is to reject any extraneous solutions from the final answer. Extraneous solutions are solutions that do not satisfy the original form of the equation because they produce untrue statements or are excluded values that cause a denominator to equal 00....
22.1 .Solving Rational Equations (性方程的求解 ) 本课程旨在增加那些在代数、基本运算、特殊乘积与因子、函数与分数方程、指数、根与二次方程 ( 课程描述) 方面背景有限的学生的知识。这些播客大多是预先录制的,通常是非常短的电影 ( 5分钟或更短 ) ,通过回答学
In summary, solving rational equations with literal coefficients is not terribly bad. We recall that a literal coefficient is a variable used to represent a number and that a rational equation is an equation with fractions made up of polynomials. Solving these problems is a two-step process. Th...
Essential Questions Solving Rational Equations and Inequalities How do we solve rational equations and inequalities? Holt McDougal Algebra 2 Holt Algebra 2 A rational inequality is an inequality that contains one or more rational expressions. You can solve rational inequalities algebraically by multiplying...
