Mathematics - "How to solve ANY quadratic math problem"

Hey there guys! Today, I'm going to show all of you how to easily solve any quadratic equation! Yes, thats right! First, you need to know how to get a quadratic problem. Look at this one: X² + 3X + 5 = 0 This is a quadratic problem. Now lets say you have this problem: X² + 3X = 5 Uh oh! This isn't a quadratic anymore! Do not worry. We can easily make it a quadratic, by doing this: X² + 3X + ¯5 = 5 + ¯5 Then it turns into: X² + 3X + 5 = 0 What we did was we had to get a 0 on the right side of the problem. To do so, we had to add 5's opposite which is ¯5. 5 plus ¯5 is 0. But what we do on one side, we must do on the other. So if we add ¯5 on one side, we must add ¯5 on the other side! Then we just work it out. You might be wondering why it came out like "X² + 3X + ¯5 = 0" instead of "X² + ¯2X = 0". The reason is because of the Hippopotamus rule. You can only add "like things" together. Only X²'s can be added to X²'s. X's can only be added to X's, and numbers can only be added to numbers. Try and make these quadratics: X² + 2X = 6 X² - 10X = 12 X² + 4X = 8 Good, now that you know how to convert, lets move on! Here is our Quadratic Formula: X = ¯B ± √B² - 4 • A • C / 2 • A Don't be afraid! It is very easy if you look at it hard enough. Lets look at a quadratic: X² + 3X + ¯5 = 0 I'm going to give each number(X², 3X and ¯5) a name tag. The name tags will be A, B and C. The first number(X²) will be A, the second(3X) is B and the third(¯5) is C. We can now add these to our Quadratic Formula. Lets look at the first part of the Formula: X = ¯B ± This is where we put our B name tag, so instead of writing "X = ¯B ±" we will write just the number, which is now "X = ¯3 ±" See? Lets do the next part: √B² - 4 Instead of writing that, we will write "√3² - 4" So this is what we have so far: X = ¯3 ± √ 3² - 4 Your doing great! Lets continue... Next, we have A • C So instead of writing that, we will write "1 • ¯5" Why did we put 1 instead of X²? Because you ONLY put the numbers. If there is no number by X², then we just put a 1. In fact, X² can also be read as 1X². Anyway, time for our last part! Here we have / 2 • A So we will write "/ 2 • 1 Lets look at our Formula again: X = ¯B ± √ B² - 4 • A • C / 2 • A So instead of that, we will write: X = ¯3 ± √ 3² - 4 • 1 • ¯5 / 2 • 1 Now lets solve it! Lets not worry about the X = ¯3 ± √ part yet. So we have now "3² - 4 • 1 • ¯5" 3² is just like saying "3 • 3", which is 9. So now its: 9 - 4 • 1 • ¯5 In math, we always multiply and divide first. 4 • 1 is 4, and then 4 • ¯5 is ¯20. If you multiply a positive number with a negative, it will be a negative, always. Negative times a negative will be a positive. Anyway, now we have 9 - ¯20, which is 29. If this confuses you, think of negative numbers as subtracting. If you have 5 - 2, the answer is 3. But you can change the 5 - 2 to 5 + ¯ 2, which is still 3. You can change a subtraction problem by instead, adding its opposite. So 9 - ¯20 can be 9 + 20, which is 29. Lets look at our problem so far: X = -3 ± √ 29 / 2 • 1 √ means "The square root of" Here are some examples: √4 is 2 (2 • 2) √9 is 3 (3 • 3) √12 is 4 (4 • 4) It is a number when multiplied by it's self. √25 is 5 (5 • 5) So the square root of 29 is around 5.4(We will round it to 5.4). So now we have: X = ¯3 ± 5.4 / 2 • 1 Lets multiply the last part, making the problem: X = ¯3 ± 5.4 / 2 The / 2 makes it a fraction by the way. All of this is over 2, like ½... So ¯3 ± 5.4 The ± means "plus or minus" You can either add the problem, or subtract it. We have to do both. Lets first add. ¯3 + 5.4 is 2.4, so we now have: X = 2.4 / 2 Now lets subtract! ¯3 - 5.4 is just like saying ¯3 + ¯5.4, which is 8.4. If you add two negative numbers, its the same as adding them. So lets look at our two answers! X = 2.4 / 2 X = ¯8.4 / 2 Congratulations! You just solved your first quadratic! If you need help with any Algebra, just ask, I'll be happy to help!
