Answer:
1) 
2) 
Step-by-step explanation:
You can factorize the quadratics equations by applying the proccedure shown below:
1) 
Find two number whose sum is 3 and whose product is 2.
These would be 1 and 2.
Rewrite it as folowing:
2) 
Find two number whose sum is 15 and whose product is 50.
These would be 5 and 10.
Therefore, you can rewrite it as folowing:
The line extends to the right, so the answer must be C or D. The dot is not filled in, which means -2 is not included in the solution. Therefore the correct answer is C: x is greater than -2.
Hope this helps.
