how do i improve myself in algebraic expressions???

Question

i cant really understand the method of doing this!! i always seem to get it wrong...

Answer 1

Honey, don't worry. I have felt your pain. I failed Algebra in highschool and never understood it one bit until I had to take what I call Dummy classes in college-
This is what I do
look at the formula- is it something like
5(X-2) if so it is equal to 5X-10

Remember my dear aunt sally
My- The letter M means multiply
Dear - means divide
Aunt - means add
Sally-means substract

You are going to do this in whatever order that they come first left to right.

Hope this helps.

Answer 2

Here is how to solve an algebraic equation:

1. Look at the equation.
2. Simplify both sides of the equal sign. This means do exponents first (like 3 to the x power), then multiply and divide, then add and subtract.
3. Next, do mathematics to both sides of the equation. If you multiply the left side by 4 then you must multiply the right side by 4. If you add (x+1) to the left side then add (x+1) to the right side. If you subtract (y^2-6) from the left side then subtract (y^2+6) from the right side.

Just do NOT multiply both sides by zero. That's the only thing that will mess you up.

Algebra is the basis for many mathematics problems to come later. Scientists, accountants, stock analysts, engineers, and many other professions rely on algebra throughout their careers.

Practice, practice, practice! When you do your math on both sides of the equation, try to put all factors with a given variable together. In other words, put all the x's with the x's, the y's, with the y's, the q's, with the q's, etc.

4n^3 + (y-7) + 2 + 3n - 2(n+4) = n^2 + 4n +2 -y.
(note: 4x^3 means "four times x cubed").
1. Multiply and divide. -2(n+4) becomes -2 times n minus 2 times 4 or -2n-8. +(y-7) becomes y-7.
2. Group everything together. Put the n's with the n's and the y's with the y's.
4n^3 +3n -2n +y-7+2-8 = n^2+4n-y+2.

4n^3 +n +y -13 = n^2 +4n-y+2.

NEXT start adding/subtracting from both sides of the equals sign so the right side equals zero.

4n^3 +n +y -13 -n^2-4n+y-2= n^2 +4n-y+2-n^2-4n+y-2

4n^3 +n +y -13 -n^2-4n+y-2=0.

put the n's with the n's and the y's with the y's again.

4n^3-n^2+n-4n+y+y-13-2=0.

I'll let you take it from there!

Answer 3

get a private math teacher and beleive me u will see yourself improving and u'll be the best in algebraic ..but u need to practice..the private teacher will gives clues and secret methods to resolve the complicated expressions..it worked with me!

Answer 4

Work on your diction.

Answer 5

just pratise
