@AshleyF tell me the two points where the curve is intersecting the x- axis?

anonymous · Answer

(0,-4)

ash2326 · Answer

Isn't it intersecting at 2 and -2?

anonymous · Answer

o yeah my bad

ash2326 · Answer

so what are the two roots?

anonymous · Answer

-2 and 2 so does it make it differences of two squares

anonymous · Answer

its a perfect square quadratic equation

ash2326 · Answer

Yeah you're right great work:D

thank you

@Siddharth18 for a perfect square, both roots need to be the same!!

@ash2326,, sorry i was in a hurry to answer and so didn't notice it.
now, this graph represents a quadratic eqn without any x term(i mean coefficient of x=0).so it reduces to the form ax^2-c=0  for some constants a and c with c/a>0.
  therefore x^2=c/a, this gives us two roots equal in magnitude but having opposite signs.
by looking at the graph one can easily see that it represents x^2-4=0 giving the two roots as 2,-2
