Question: Factoring math problems?

I was gone when we where taught how to factor, so could someone explain to me how.

i have like 4 worksheets due tomorrow and no clue how t do them, so ill give you the titles of the w/e and some ex from each.

FACTOR COMPLETELY.
1. 10x+35
14. 36a^3-24a^4+60a

FACTOR USING DISTRIBUTIVE PROPERTY.
complete/fill in the blanks
1. 8m-6=2(4m-___)
4. 5a^2b-a0a^2b^=____(1-2b)

FACTOR EACH POLYNOMIAL.
1.5a^2-15
10. 75b^2c^3=60bc^6

FACTOR.
1. 10a-18b
30.x^3y^2z^5-5x^2y^2z^2+12x^5y^2z^2
34. 22a^2b-44a^2b^3+66ab^4

please don’t just give the answer, explain =]
thanks soooo much
you don’t know how much i appreciate it.
i’m pretty sure they are written out right :/

Answer: FACTOR COMPLETELY
The first thing you have to do when you factor, is take out the GCF(Greatest Common Factor), if there is one. For these two problems, that’s all you can do.
1. 10x+35
What is the largest number that can go into both 10x and 35?
5, right?
5(2x+7)
If you dristibuted this back out, you would see it comes out to the same thing. It’s just a simpler way to write it.
14. 36a^3-24a^4+60a
Take out the GCF, which is 6a.
6a(6a^2-4a^3+10)
Rearrange the term inside the parenthesis so that the exponents go from greatest to least.
6a(-4a^3+6a^2+10)

FACTOR USING DISTRIBUTIVE PROPERTY
1.This is basically the same thing. They’re taking out 2 as the GCF.
8m-6=2(4m-3)
4. Are you sure you wrote down this problem right?

FACTOR EACH POLYNOMIAL
1. Still just taking out the GCF.
5(a^2-3)
10. Subtract 60bc^6 from both sides to make the equation equal 0.
75b^2c^2-60bc^6=0
Take out the GCF, 15bc^3.
15bc^3(5b-4c^3)

FACTOR
1. Take out the GCF, 2.
2(5a-9b)
30. What????? Are you sure you wrote the problem down right?
34. Are you sure you’re writing these down correctly? That doesn’t make sense.

Question: Ks3 SAT’S – Help?

I’ve started to revise for my SAT’s but I don’t think I’m really learning anything because all of the things I don’t understand or remember stay unknown, even with the revising.
I’m reading my revision books , doing worksheets and getting my Mum to test me but I don’t think it’s actually doing anything benifitial because what I need to remember is the harder subjects, eg. trig.

How can I get the information to really sink in?

Please don’t sugest bitesize because I might commit a murder if you do.
(Oh and for my mock SATs I got :
Science : 7
English : 7 for both
Maths :

I’m sorry if I’ve waisted anyone’s time, I hope you can help me anyway. Thank you

Answer: Stop panicking, just do your best. KS testing seems largely for the sake of the school – to keep them well up in the league tables. Getting a good score will make you feel good, but your form placements at KS4 will already have been made on the basis of your performance and tutor assessments – much more reliable than small ‘snapshots’ of your performance during SATs.
As for revision advice, try writing out the bits you find really difficult, gradually condensing them to bullet points and if possible down to acronyms (just initials) that make single words or phrases to represent whole concepts.
Good luck with your GCSEs. you’re bound to do them if you’re this worried about SATs…
