It will be irrational. The sum of any irrational and rational number will ALWAYS result in a irrational answer. Khan Academy has a video on this if you want to watch it.
Answer:
Minimum: (2,4)
Step-by-step explanation:
h(x)=3(
-4x)+16
=3(-4x+4-4)+16 (- For the balance of equation, and attention 1)
=3
-3*4+16
=3+4
<h3>Attention:</h3>
1. 
2. The formula for the vertex form is y = 
, the vertex is (h,k)
Answer:
There is exactly one more real solution or there is exactly one more complex solution
Step-by-step explanation:
A quadratic equation is a polynomial of degree two
What this means is that a polynomial has two answers.
Now, from the question, we have an answer already which is a real root
Then the other answer which we do not have can take the form of two answers
It can either be a complex root or other wise be a real root
So the answer to this question is that ;
There is exactly one more real solution or there is exactly one more complex solution
Her answer is wrong because the product of 78.112 = 8736.
