Answer:
70/9
Step-by-step explanation:
We have the quadratic:
So, let’s find the roots of the quadratic. We will set the expression equal to 0:
Testing for factors, we can see that our quadratic isn’t factorable.
So, we can use the Quadratic Formula. The quadratic formula is given by:
In this case:
Therefore, by substitution:
Evaluate:
Simplify the square root:
Hence:
Reduce:
So, our roots are:
We want to find the sum of the <em>squares</em> of our two roots. So, let’s square each term:
Square. For the numerator, we can use the perfect square trinomial patten where:
Therefore:
Simplify:
Similarly, for the second root, we will have:
So:
Simplify:
Therefore, our sum will be:
Therefore, our final answer is 70/9.
A conclusion can be made that nobody on brainly knows what that sentence means

if my answer is wrong i'm sorry here is a manual on how to do it if its wrong
i think they are right but just in case
Identify the output values. If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.
1 relation
2 function
3 relation
4 function
i know 4 is right but i don't know about others double check i suggest just in case i think they are right
