11.
a=1 b=4 c=2
d= 16-8
=8
solving by quadratic formula
after substituting the value you will obtain
x=
12.
x - 1 is a factor of 4x^3 + 3x^2 -4x +k
then x=1 is one root of 4x^3 + 3x^2 -4x +k
put x= 1
4x^3 +3x^2 -4x +k = 0
=> 4 (1)^3 +3 (1)^2-4 (1) +k =0
=> 4 + 3 - 4 + k = 0
=> k = -3
13. whole number = 0,1,2,3......
natural number = 1,2,3...........

Answer:
11.The answer to the first question is 2 because the degree of the polynomial is 2 (a quadratic polynomial)...
12.The answer to this question is, that the value of k= -3
13. True. Every whole number, is a natural number! The collection of whole numbers include natural numbers along with 'zero'
