Question

solve -x^2=4x by graphing

Answer 1

it is a qudratic equation

Answer 2

taking x^2 on other side

Answer 3

x^2+4x=0
can u do it now??

Answer 4

you need to graph 2 curves

\[y = 4x ~~~ and~~~~ y = -x^2\]

and find the points of intersection...

you can use a table of values

perhaps x = -4 to x = 4 for the parabola... so you see the shape, and then pehaps

x = 0, x = 1 and x = 2 for y = 4x.

Hope it helps
