In factoring a complete equation what am I doing wrong on my test i messed 8 and it made me flunk the test. These are a example of some probelms:
1. 3a^2-21a+18
first you would find the common demonantor whcih would be 3 the answer that i got was 3(a-6)(a-1) is this correct?
2. 9x^2 =25x-6
the answer that I got was (9x-2)(x+3)?
3. 4a^2b^3+ab^4-4ab^4-b^5
the answer that i got is (4ab^3=b^4)(a-b) is this right?
4. b^2-7b-44
the answer is (b+22)(b-2)?
5. 45a^3d-75a^2d^2-30ad^3
the answer that I got is 15ad(3a+d)(a-2d) is this right?
6. 3x^2-x-10
the answer is (3x-5)(x=2) is this right?
7. 2x^2-10x-28
the answer will be 2(x-2)(x+7) is this right?
Thanks for all your help I really apprecaite it alot. Maybe I can use this site for my family
