### How To: Make a factor tree for the numbers 12 and 5

Making a factor tree is useful for us to see the factors of those numbers. Here we will take 12 and make a factor tree of it. Now we have to see those numbers with whom multiplication 12 comes. We will not take 1 and 12 here that is a obvious answer. We will take 3 and 4 there multiplication is 12. It will make the first branch of the tree now for the next branch we will take 3. 3 is a prime number 4 is not a prime number but multiplying 3*2*2 gives 12.

### How To: Reduce and simplify fractions

In this tutorial, we learn how to reduce and simplify fractions. When you do this, you want to make sure you have taken common factors out of the top and bottom, then divide them out until the only common factor is the number one. You will keep going until you get to this point, or you can do another method by finding the greatest common factor. To understand this better, take the example of 24/64. The greatest common factor of these numbers is 8, because it divides evenly into both of them. ...

### How To: Solve rational equations easily

This video revolves around solving rational equations in Algebra 2. When you are given a rational equation, you have to find the greatest common factor and multiply all fractions to get that common factor. If a fraction already has that common factor, then no further step is necessary for that one. Next, you have to multiply all fractions by the greatest common factor to get rid of all denominators. Finally, the remaining equation is simple math and you only need to solve the equation for the...

### How To: Factor the difference of squares

In this video the instructor shows how to factor the difference of squares using a formula. The formula to find the difference of squares can only be applied if you have two perfect squares. The formula is (a * a - b * b) = (a - b) * (a + b). That is the difference of squares of two numbers is the product of sum of two numbers and difference of two numbers. So when you need to find the difference of squares of two numbers substitute the values in the above formula to directly solve for the fa...

### How To: Factor & find zeros of a polynomial

This is the video about how to Factor & find zeros of a polynomial. How did I know that x=1 and x=-1 were roots of the polynomial. Suppose the polynomial has a rational root, let's call it. I will assume that p and q are co prime, i.e., the fraction is reduced to lowest terms. What we will be doing is somewhat similar to "factoring by guessing" of quadratic polynomials. Since is assumed to be a root of P(x), we know that if we multiply both sides by, we obtain: Transfer them to the other side...

### How To: Use the Grouping factoring method

This video is about using the grouping factoring method. We're using a four term polynomial. There is a even number of terms. We can break them into two groups of 2. The first group of "2" the common factor is "a." The last group, the common factor is "-2b". The reason we use -2b is to assure that what is in the first group is the same as the second group. Because of the distributive property of multiplication over addition, we take the a-2b and put it in one bracket. Multiply by 3x+1. With 6...

### How To: Reduce fractions

This video shows you how to easily reduce fractions. A fraction contains a numerator and a denominator. The numerator is the number on the top and the denominator is the number at the bottom of the fraction. The first thing you have to do to reduce fractions is look for the greatest common factor between the numerator and the denominator and divide both top and bottom of the fraction by that common factor. (e.g.. 18/24 - the greatest common factor is 6 => (18/6)/(24/6)= 3/4. Continue reducing...
