Answer:
The roots are
<h3>
</h3>
Step-by-step explanation:
9x² + 54x + 82 = 0
Using the quadratic formula
That's
<h3>
</h3>
From the question
a = 9 , b = 54 , c = 82
Substitute the values into the above formula and solve
That's
<h3>
</h3>
Separate the real and imaginary parts
That's
<h3>
</h3>
We have the final answer as

Next four multipules of 4/8
to keep the value of 4/8 the same, we must multiply the top number and bottom number by the same thing
4/8 times 2/2=8/16
4/8 times 3/3=12/24
4/8 times 4/4=16/32
4/8 times 5/5=20/40
next 4 multipulees are
8/16, 12/24, 16/32, 20/40
