plz answer this question it's very important​

Answer 1

Answer:

MARK ME AS BRAINLIST

Step-by-step explanation:

9. d .none of the above

10. b . 1

11.d

12. b

Answer 2

Answer:

9.D, 10.A, 11.B, 12.B

Step-by-step explanation:

9. Zeros of x²–3 are

x²–3 = 0

x² = 3

X = + root 3 or –root 3 - [d]

10. The number of zeros of the polynomial in the graph are none (0) because the points of the polynomial does not intersect x-axis at any point so there are no zeroes for the polynomial. - [A]

11. according to question

lets consider

a + b = -3

a × b = 2

to find quadratic polynomial there is a formula that is :

polynomial = k [ x² - (a+b)x + ab ]

= k [ x² - (-3)x + 2 ]

= k [ x² + 3x + 2 ]

if the value of k is 1 then the required polynomial is

X² + 3X + 2. - [ B ]

12. cannot both be negative. - [B]

Hope this helps you.
