I've had so many bad experiences with math,perhaps even having dyscalculia.I went to a terrible school that never taught.Now,I go to a great school that actually teaches.I wouldn't say I passed Algebra 1,my old school passes anyone,and I never really learned Algebra.Now in my current new school I'm going to be a junior and taking Algebra 2! I'm nervous,stress etc.I have till August 20th to learn on my own.I downloaded an Algebra Basic Software.And it's incredible it taught me well! So this is what I learned to do so far,I still got a lot to go..right? :(
---------------------------------------------------------------------------
Rules to remember:
1.Multiplication or division of two terms with similar signs will result in a positive term.
2.Multiplication or division of two terms with different signs will result in a negative term.

Then,they gave me problems to slove like these and i can't believe I got them right.maybe I can do algebra?

10 c x ( -7d) = -70cd

or 3d x ( - 8 e)= 24de

Simplify: (1/2x)+(2/x-1)

The answer is (5x-1)/(2x^2-2x)

Please show how to work this out

I tryed to foil Evaluate/Simplify: ( x - 1) (2x + 3) but I seem to end up with 2x^2+3x-x-2 but the answer is 2x^2 + x - 3. Where did I go wrong?

Find:
a. roots of the function
b. zero of the function

1)x^2 - 5x + 6 = 0

2)x^2 - 10x = -21

3)x^2 - x -6 = 0

4)x^2 + 4x = 5

5)2x^2 + 2x = 4

6)-x^2 + 4x - 3=0

Show solutions / reasons. Thanks.
