This equation can be solved using the quadratic formula
Option D:

Rewriting we have:

It can not be solved with the quadratic formula.
Answer:
A and C
Hi, where are the graphs?
The answer would be 0,0 because the dotted line is a negative slope to the right, intersecting the y axis at 2 and the shading is below.
9x+3. you have to combine like terms.
