How do you know if you will subtract or add in simplifying algebraic expressions?

Only like terms can be subtracted or added in algebraic expressions.


How is doing operations with rational expressions similar or different from doing equations with fractions and how can they be used in real life?

How is doing operations (adding, subtracting, multiplying, and dividing) with rational expressions similar to or different from doing operations with fractions?If you know how to do arithmetic with rational numbers you will understand the arithmetic with rational functions! Doing operations (adding, subtracting, multiplying, and dividing) is very similar. When you areadding or subtracting they both require a common denominator. When multiplying or dividing it works the same for instance reducing by factoring. Operations on rational expressions is similar to doing operations on fractions. You have to come up with a common denominator in order to add or subtract. To multiply the numerators and denominators separated. In division you flip the second fraction and multiply. The difference is that rational expressions can have variable letters and powers in them.


To add two rational expressions that have the same denominator you simply add the?

You add the numerators and put over the denominator.


Finding the LCD of rational algebraic expressions?

LCD is probably a typo for LCM. The least common divisor of any number is 0 since 0 is the smallest natural number and divides all numbers.The LCM of two rational algebraic expressions is often used to add or subtract the two expressions. The method used is to identify all common factors in the denominator of the expressions, and multiply the numerators by the uncommon factors (exactly like you would for non-algebraic fractions).example:(2/(a+b)xyz) + (4/(a+b)cdz)the common factors are (a+b), and z. You must multiply the left expression by cd, and the right expression by xy to get(2cd+4xy) / (a+b)cdxyz


After you add or subtract two rational expressions it's a good idea to see if you can your answer?

reduce


How do flowcharts help building up algebraic expressions?

Because they add onto the expression with every step.


How do you add and subtract algebraic expressions for example My homework says which expression represents the perimeter in units of this trapezoid?

To add and subtract algebraic expressions the simple rule of like terms applies. In your homework that asks for the expression represents the perimeter in units of this trapezoid you will need to find the like terms and simplify.


How do you Add rational expressions with common denominators and binomial numerators?

If the denominator is the same, you just add the numerators - just as with plain numbers.


After you add or subtract two rational expressions the next step is to put your answer in form?

reduced form $ara ;)


After you add or subtract two rational expressions its a good idea to see if you can your answer?

You should check whether you can simplify the answer.


How is combining like terms similar to adding and subtracting square roots?

In surd form, square roots need to be have the same radical term before you can add or subtract them. However, unlike in algebraic expressions, it is possible to add or subtract square roots using approximate (decimal) values.


How do you solve 1.50p plus 2.50p plus 3p This is a simplifying algebraic expressions and add subtract integer problem?

It is: 1.50p+2.50p+3p = 7p when simplified
