This question comes from ch.7.3 titled :Adding and subtracting rational Expressions with the same denominator and least common denominator.
I'be tried this problem several times and keep getting stuck. I don't think I'm starting it right.
I've multiplied it out so that they both have a common denominator of (x+4)(x-2) and now I'm confused on what to do next.
Rationalize the denominator in the expression -√2d t = ---- ...
need to find the domain for both expressions g^2 - 6g-55 divided by g k^3 + k divided by K^2 + k - 42
Simplify this rational expression x^2+3x-7 x^2+5x-9 x^2-6x+14 ----------- - ------------- + --------------- x^2-2x-8...
I need help with adding and subtracting rational expressions
(FIRST PART ALREADY ANSWERED AND NEW PART ADDED) Why do you find the domain of both the numerator and denominator in a rational equation? When do you do it?
For example, if you had: x-3 ------ 5x+3 you'd only find the domain and use the denominator. Why wouldn't you also do the numerator? And...
determine value of k when g(x)= 4x+k does not intersect the parabola f(x)=-3x2-x+4
Simplify the rational expression (Show All work) x^2-8x-48/x+4
I have a few questions on my pre - test study guide that is due tomorrow that I don't understand how to do. I am in math 120 or in algebra 2 for high school - but i am a college student. I have...
The problem is (2x+1/3)-(x-5/4)=1/2
The problem is : (3x+3/x^2+2x+1)+(x-1/x^2-1) ^2=squared ive been on a lot of math help websites but I cant seem to figure out how to solve this
Combine the rational expressions.. Reduce your answer to lowest terms 2/x2 + 5x + 6 - 4/x2 + 4x + 3 + 3/x2...
1/x + 1/9 / 1xsquare - 1/3
Adding and Subtracting Rational Expressions 5 over 6ab - 7 over 8a after getting common denominators i get 20 - 21b over 24ab can this be further simpified?
How is the process for simplifying and multiplying fractions similar to simplifying or multiplying rational expressions?
How is the process for simplifying 2x(x+1)/4(x+1) similar? Different?
How is adding, subtracting, multiplying and dividing fractions similar to doing the same with rational expressions. can you give me an example of each?
