<h2>
Step-by-step explanation:</h2>
<h2>Therefore, finding the discriminant:</h2>
<h3>a = 3 b = -4 c = 164</h3>
<h3>We, know that to find discriminant. </h3>
<h3>b^2 - 4.a.c</h3>
<h3>(-4)^2-4.3.164</h3>
<h3>-8 - 1968</h3>
<h3>- 1976</h3>

Answer:
6x4
Step-by-step explanation:
Her equation doesn't fit the word problem! It says several 2 pounds books but she put it as if there was one. She should have wrote the equation like this:
3 + 2x = 20 (where x represents the unknown amount of boxes)
and than you can just solve for x to find how many books there are
3 + 2x = 20
2x = 20
x = 10
So there are 10 books!
I hope that helps! Let me know if you have any questions :3
Answer with Step-by-step explanation:
Let F be a field .Suppose 
and 
We have to prove that a has unique multiplicative inverse.
Suppose a has two inverses b and c
Then, 
where 1 =Multiplicative identity
(cancel a on both sides)
Hence, a has unique multiplicative inverse.
