Explain why the graphing calculator cannot be used to solve or approximate solutions to all polynomial equations.
2 answers:
Did your explanation include the following?
Some polynomial equations have complex solutions.
Therefore, complex solutions cannot be found by graphing the related system or function in the Cartesian (x-y) plane.
Polynomial functions with all complex solutions do not have x-intercepts, and the related system of equations will not intersect.

the answer to your problem is 0.8
Answer:
Dont think eh multiplied both sides by 4. That would be the first step.
Step-by-step explanation:
1/4(x+12)=2
multiply both sides by 4
x+12=8
move the 8 to the right side of the equation and change its sign
x=8-12
calculate
x= -4
