The solutions to nx^2 + px + q=0 are 4 and -2/5. What information does this tell you about the graph of f(x)= nx^2 + px +q?

Question

If you could answer this for me, that would be great. Thanks in advance :)

Answer 1

all it tells me is that it is a parabola that crosses the x-axis at 4 and -2/5.
