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.
