If x = 1 is a zero of the polynomial 3+ kx^2 + 2 ,find the value of k.

Plz it's urgent.

k = i√ 5 , -i√ 5

Step-by-step explanation:

3 + kx^2 + 2 = ?

3 + k(1)^2 + 2 = ?

5 + k(1)^2 = ?

5 + k^2 = ?

k^2 = -5

k = i√ 5 , -i√ 5

option 2

Step-by-step explanation:

Hi, to answer this question we have to solve the inequality given for x:

-1/2x ≥4

x ≤4/-(1/2)

x ≤ -8

So, the solution are all the numbers less (more negative) or equal to -8.

The second number line represents the solution set for the inequality
