Answer: k = {8, -8}
<u>Step-by-step explanation:</u>
In order for a quadratic equation to have exactly one solution, the discriminant must equal zero. → b² - 4ac = 0
4x² + kx + 4 = 0
↓ ↓ ↓
a=4 b=k c=4
b² - 4ac = 0
k² - 4(4)(4) = 0
k² = 64
k = √64
k = ± 8
Hi There!
Change all the fractions to decimal you do that by dividing numerator by the denominator. Remember

as a decimal is 0.5
A=

= 0.43
B=

= 0.60
C=

= 0.8
D=

= 0.42
E=

= 0.6
Based, on the data above B,C,E are greater than

because they all have decimals greater than 0.5, B= 0.6, C= 0.8, E=0.6
So,

are all greater than

Hope This Helps :)
