Division is the splitting of large numbers (in this case) numbers into equal groups of smaller numbers. Here are some terms you need to understand before you divide: The number being divided is called the <em><u>dividend</u></em>. The number that you're dividing by is called the <u><em>divisor</em></u>. The answer that you get to the division problem is called the <em><u>quotient</u></em>.
For example: Let's try dividing 4 ÷ 2 . Since 4 is the number being divided, it is the <em>dividend</em>. And since were are dividing 4 (the dividend) by 2, 2 is the <em>divisor</em>. We need to try and find the quotient to solve 4 ÷ 2 .
Think of it this way; There are 6 cookies and we need to divide them equally so that 2 people can have the same amount of cookies. 6 ÷ 2 = 3 You know the answer is 3 because 2 goes into 6 three times. 2 × 3= 6 (Since you asked a question about division, I'm guessing you know multiplication.) 3 for one person and 3 for the other. So how many does each person get? 3 cookies, fair and square. A nice way to check this problems is fact families, as I have mentioned before with the multiplication problem.

In your problem a = 1, b = -4 and c = 5 so discriminant is -4 the discriminat is the value under the radical so if the number is negative there is no real solution. if the number is 0 there is one solution if the number is positive there are two solutions
