Simplify: \frac{4x^2 + 9x - 2}{x^2 + x - 2} \cdot \frac{x^2 - 1}{3x^2 + x - 2} How to simplify 2x^2 - 4? Let f(x) = 2x^2 - 3x^2 - 3x + 4, \; g(x) = x^2 -1. Find and simplify f(x) \cdot g(x). ...
Since - 8x and 15x are similar terms, we may combine them to obtain 7x. In this example we were able to combine two of the terms to simplify the final answer. Here again we combined some terms to simplify the final answer. Note that the order of terms in the final answer does not ...
Theorem 1 ;Ifa EN, and b EN, then 2¢- x = z+ We may use this theorem and our previous axioms about the set of real numbers to simplify many algebraic expressions as the following examples illustrate.Example 2 Find the standard form....
Solution We need to add the amounts of the three checks and subtract the sum from the original balance. We therefore write $567.19 - ($18.50 + $24.95 + $129.40) = $567.19 - $172.85 = $394.34. The first step is to simplify what is inside the parentheses. ...
There are few rules of logarithms you will need to know to solve this question. They are: b(a)+logb(c)=logb(ac)logb(a)−logb(c)=logb(a/c)clogba=logb(ac)logbb=1 Answer and Explanation: Learn more about this topic: ...
