2970
Step-by-step explanation:
Cost price of a table is 3300
Loss percentage during the sale transaction = 10%
So the loss incurred during the transaction = 10% of 3300
=![\[\frac{10}{100}*3300\]](/tpl/images/0504/3781/771da.png)
=![\[\frac{33000}{100}\]](/tpl/images/0504/3781/fe918.png)
= 330
So the selling price of the table = Cost Price - Loss
= 3300 - 330
= 2970
Hnce, the selling price of the table sold at a loss of 10% is calculated as 2970.

The easiest way to determine if a quadratic equation has real solutions is by using the discriminant.
Start by finding a,b and c. You can find a by looking at the coefficient of x^2. You can find b by looking at the coefficient of x. You can find c by looking at the constant at the end.
Now use the discriminant formula.
b^2 - 4ac
After plugging in and solving, check the number. If it is negative, there are no real solutions. If it is positive there are 2 solutions. If it is 0, there is one real answer and it is a double root.
