Just took the quiz. The answer is (-1, -3) (1, -3)
Answer:it’s 80
Step-by-step explanation:
It would be B. "Regular" factoring without the quadratic formula can't be done. Completing the square will work easily since the coefficient on the squared term is a 1. I personally wouldn't graph this to find the solutions, although you could with and x/y chart to give you enough coordinates to plot the graph correctly.
Since the topic is similar right triangles you need to think of the Pythagorean triples, for this problem use the 3-4-5 triplet ratio
