B and have a good day
The roots of the quadratic equation are:
x = 0.74 - 0.6614i
x = 0.74 + 0.6614i
The given equation is:
2x² + 2 = 3x
Rearrange the equation
2x² -3x = -2
Divide through by 2
x² - (3/2)x = -1
x² - (3/2)x + (3/4)² = -1 + (3/4)²
(x - 3/4)² = -7/16
Square root both sides
x - 3/4 = √(-7/16)
x = 3/4 ± √(-7) / 4
x = 0.75 ± i√(7) / 4
x = 0.74 ± 0.6614i
Therefore, the roots of the quadratic equation are:
x = 0.74 - 0.6614i
x = 0.74 + 0.6614i

Answer: There are 64 relations from A to B.
Step-by-step explanation:
Number of relation from set A to B = 
Since, A={Φ,{Φ},{Φ,{Φ}}} and B={1,2}
i.e. Number of elements in set A = 3
Number of elements in set B = 2
So, Number of relation from set A to B = 
Hence, there are 64 relations from A to B.

Step-by-step explanation:
The angle m∠AFE is 128 degrees.
<h3>How to find angles?</h3>
∠AFB ≅ ∠EFD
∠EFD = 5x + 6
m∠DFC = (19x - 15)°
m∠EFC = (17x + 19)°
m∠AFE = ?
m∠AFB + m ∠EFD + m∠AFE = 180
Therefore,
5x + 6 + 5x + 6 + m∠AFE = 180
5x + 5x + 6 + 6 + m∠AFE = 180
10x + 12 + m∠AFE = 180
10x + m∠AFE = 180 - 12
10x + m∠AFE = 168
m∠AFE = 168 - 10x
m∠EFC = m ∠EFD + m∠DFC
17x + 19 = 5x + 6 + 19x - 15
17x - 5x - 19x = 6 - 15 - 19
-7x = - 28
x = 28 / 7
x = 4
Therefore,
m∠AFE = 168 - 10x
m∠AFE = 168 - 10(4)
m∠AFE = 168 - 40
m∠AFE = 128°
Therefore, the angle m∠AFE = 128°
