Answer is B

Yashi Shakhla answered Aug 19, 2020
The equation has maximum degree of 2 than the maximum zeros will be also 2 . That's why answer is 2....HOPE IT HELPS.

Aradhiya Gupta answered Aug 05, 2020
Two zeros have in the equation because it has the highest degree of two

Man Oj answered Jul 27, 2020
Since it is a quadratic equation it will have two zeros

Saurabh Sharma answered Sep 26, 2020
The above no. have the degree 2 . so we know that when degree is 2 than the no. of zeros is also 2

Riya Verma answered Aug 23, 2020
The zeroes of polynomial depends on degree . As the degree of the polynomial is 2 , there will 2 zeroes of polynomial.

Divya Upadhyay answered Sep 26, 2020
Answer is (b) correct. Because the degree of this polynomial is
2. So the maximum solution of this polynomial is 2

Sanidhya Jhalani answered Aug 17, 2020

The given equation has 2 zeros therefore, the degree of this polynomial is 2

Seema Bajpai answered May 13, 2020
B is the answer

Rajat Singh answered Aug 16, 2020
The zeros will be 2 because it is a quadratic equation.

Yathartha answered Sep 06, 2020
Correct answer is B

Sai Vishesh Gondhi answered Sep 06, 2020
As it is quadratic equation i.e the degree of polynomial is 2
Therefore the no. of zeros is 2

Tanisha Kunwar answered Sep 04, 2020
No. of zeros will be 2 'B' since it is a quadratic equation.

Somenath Lahiri answered Aug 18, 2020
In the quadratic, D= b²-4ac = 4²-4×1×2=8
Since D is greater than zero, the eqn has two roots
which are -2±√2

Omkar Kadam answered Aug 07, 2020
B is correct answer

Srushti Gunjal answered Sep 06, 2020
A equation having 2 variables always has infinite zero..

Khushboo Bishnoi answered Aug 29, 2020
It is a quadratic polynomial that's why the answer is option b...
