Hello,
The value of k is 6.
Explanation
1. Understand the Formula
For any quadratic polynomial in the standard form ax² + bx + c, the product of its zeroes (roots) is given by the formula:
Product of the zeroes = c/a
2. Identify the Coefficients
First, let's identify the values of a, b, and c from your given polynomial:
p(x) = 2x² - 3x + k
Comparing this to the standard form, we have:
• a = 2
• b = -3
• c = k
3. Set Up the Equation
The problem states that the product of the zeroes is 3.
Using the formula, we know the product of the zeroes is also c/a. So, we can set up the following equation:
c/a = 3
4. Solve for k
Now, substitute the values of 'a' and 'c' from the polynomial into the equation:
k/2 = 3
To find k, multiply both sides of the equation by 2:
k = 3 * 2
k = 6
Therefore, the value of k is 6.
Hii Vidisha!
If you are asking about any national level entrance then please do specify the name of entrance exam so that I can check and notify you.
Otherwise if you are asking for any private school or goverment school entrance exam then you must check the expected dates from their websites or by directly visiting the school. It would be a more accurate and practical way of knowing tentative date.

Crop production management is a comprehensive approach to efficiently managing the various resources and activities involved in growing crops to achieve the highest possible yield, quality, and profit.
Its main goal is to get the best quality and quantity of produce—like food grains, vegetables, and fruits—in a sustainable and cost-effective way. Think of it like being the manager of a factory, but instead of machines, you are managing natural resources like soil, water, and plants to create a final product: the crop.
Hello
If you are aiming for JEE, both Presidency South and DPS South with Allen integration are solid.
Allen is strong for JEE prep, but the school environment and faculty make a big difference. Check past results and check for the best results among those campuses. Go where you can learn, grab opportunities, and make a competition because surviving is not enough; learning matters. Visit both campuses and then choose where to go.
