### Looking for practice problems for algebra ?

Can someone recommend me some books that have practice problems for algebra ?

### Re: Looking for practice problems for algebra ?

Uh,

Which algebra?

Do you mean like, "solve for x" or like, "prove that the degree of x divides the degree of the group", or something else?

I found my old forum signature to be awkward, so I'm changing it to this until I pick a better one.

High school , usual college , like that of the algebra 2 dummies .

I have one book with lots of practice problems , its called 1001 practice problems of algebra for dummies , but the book has only questions , no answers .

That sort of algebra

Another thought for you is to make up your own problems by starting from the answer. Factoring problems come to mind.

The answer is: (x-4)(x+5)

To get to the problem, multiply them:

(x-4)(x+5)

x(x+5) - 4(x+5)

(x

(x

x

Do a bunch like that, and then come back later to factor them. See if you can factor {this example} back into (x-4)(x+5)

If you get stuck, you can go back to the work where you generated the problem to begin with; it will have a roadmap to the result you want.

(It is possible that you made a mistake in multiplying them originally, so if one side looks right, check the other side)

A lot of insight into math can be obtained this way - start from the answer (or at least the form of the answer) and see how that turns into the question. Then go backwards.

(x

^{2}+ 5x ) - (4x + 20)(x

^{2}+ 5x + -4x + -20)x

^{2}-x -20Do a bunch like that, and then come back later to factor them. See if you can factor {this example} back into (x-4)(x+5)

Thanks , That is really a good idea .

I found this book a while ago online , Glencoe-Algebra 1-McGraw-Hill .Looks really good . it has lots of practice problems with answers

### Re: Looking for practice problems for algebra ?

I second ucim's recommendation of making up your own problems. Going through this process and getting familiar with it can really help your understanding of *why* the methods used to solve the original factoring problem work the way they do.

double epsilon = -.0000001;

It has lots of good practice problems too
