Answer: the answer is (2,-4) if that's not the answer then can u post a full picture of the question
Step-by-step explanation:
8x2=16, 16 over 3 is roughly 5.33. so 5 is roughly 2/3rds of 8. Use basic cross multiplication
For the one on the left they are corresponding and on the right they are vertical
First set everything to 0.

Giving you A= 1 , B= 1 and C= -5
Then input everything into the quadratic formula and either solve by hand or use a calculator.
Note exact values are found by hand, decimals are found using a calculator.
