Are you sure you want to delete this answer? I used to struggle with these. A simple way to go about solving quadratic equations, and a way that has always served me well, is to manipulate the equation to a form that you are comfortable with. For question 1 , we have: We could actually use the qradratic formula, but there is an even simplier method. To factor, you need to think of two numbers that multiply together to give c, and also add up to give b. Essentially, you have a few options because you are looking for two numbers that multiply to give and add up to give 1.
Here are some options: These are the final answers. Always remember that when you have a variable x , n, a ,c, or whatever raised to the power of 2, there are always two values to be found. For this one, you're going to want to find two multiples of that, when added together, equal the middle constant. Basically, that is the constant in front of n. Now, look at the various multiples of Also, since 12 is negative, that means one of the multiples must be negative.
Therefore, -3 and 4 are the correct numbers. After you've figured that out, you'll split the quadratic into two equations. Since we know what the two multiples are, these equations will be: This one's a little bit easier. Take the 6n and bring it over to the other side of the equation, so that everything is equal to zero.
Again, let's move everything onto one side of the equation so that it is all equal to zero. Once again, the first thing you do is figure out the multiples of 5. In this case, we only have two to work with, given that 5 is prime: A helpful scientific calculator that runs in your web browser window. Solving a quadratic by factoring.

Similarly, in the sentence 7x x, both 7 and 21 have the factor 7 in common, and each term of the polynomial also has the factor x in common. Factoring for 7x involves division by 7x, so that 7x 3 /7x equals x 2 and 21x/7x equals 3.
