Question

*²–8x+2=0 या वर्गसमीकरणाच्या मुळांची बेरीज किती?*

1️⃣ 8
2️⃣ -8
3️⃣ -2
4️⃣ 6​

Answer 1

SOLUTION

TO CHOOSE THE CORRECT OPTION

The sum of the zeroes of the quadratic equation

$\sf{ {x}^{2} - 8x + 2 = 0}$

1. 8

2. - 8

3. - 2

4. 6

CONCEPT TO BE IMPLEMENTED

If the Sum of zeroes and Product of the zeroes of a quadratic equation is given then the quadratic equation is

$\sf{ {x}^{2} -(Sum \: of \: the \: zeroes )x + Product \: of \: the \: zeroes = 0}$

EVALUATION

Here the given Quadratic equation is

$\sf{ {x}^{2} - 8x + 2 = 0}$

Now Comparing with the equation

$\sf{ {x}^{2} -(Sum \: of \: the \: zeroes )x + Product \: of \: the \: zeroes = 0}$

We get

Sum of the zeroes = 8

Product of the Zeroes = 2

FINAL ANSWER

Hence the correct option is 1. 8
