This section is all Algebra and up so you can get an understanding of the basics. If you want to know more just check out the link for About Us at the top. If any of this seems to advanced you might want to check out my other Pre-Algebra webstie to help you understand the basics.
To solve it you must put together the similars. The similars are the numbers with the same variable, the variables are x or x2 So when you add all the similars up it should look like this.
7x3+25x2-8x-5That was a pretty easy and it applies the same with subtracting except obviously you minus instead of add. Now we are moving onto division and multiplication.
To solve this is pretty straight forward, you multiply everything, but when multiplying the 2nd and 3rd power is different. To multiply the powers you add them, since they are basically multiplied themselves you add or subtract them instead of mutiplying. This below is the answer.
35x5Now onto the last section, division.
To solve this you simply divide except when you divide the powers you minus or add them depending on what it is. This is what it would look like it the process.
lass="s">27x4-2Now you minus the powers and then just divide 27 by 9. Now simplifying it, it would look like this.
3x2This is the process to solve if you have say multiple variables like this one below.
56x3y2÷ 8x2y This one is a little more complicated, but it is exactly the same to solve, but you do x3-2and y2-1 If you're wondering where the one came from, it's what the y, but when there is no power written it is automatically 1. Here is another example of the same question above, but slightly different. 56x2y÷ 8x4y3As you probably know when you divide the powers on the variables the will become negative. You cannot just leave them negative and the way to solve it is to minus what you can and leave the rest on the bottom. Like this below.
56÷8x2y2Now you simplify and get this below
7÷x2y2This is the same principle for any amount of variables, and if the variable on the bottom is negative to start with you add on because when you minus negative numbers you add them.
Here are some practice questions.
Put your answer in the box and press submit.
If you can't figure it out give up, or read again.
To supplement the second and third power you can just
write like 5x^3, 5^2, 23^4 or any exponent whenever you need to.
When you have 1x you just write x and not the one.
If you have a division problem that is not a whole number write
as 11/93, 27x/37 or other variants of this.
