Question

is it necessary that in a polynomial graph the point at which the line intersects x axis is the zero of the polynomial plz tell correct ans​

Answer 1

Yes, I think its necessary.

As, when a line meets at x-axis the y coordinate is 0 and x coordinate has some value.

When both the values are inserted in the equation it gives 0 which means they are the solution of the that polynomial.

Also, every point of the graph from where the curve or line of graph passes is a solution of that equation.

For instance the point x = 1 and y = 0 is a solution of that polynomial of whose graph is drawn below in the AttaChmeNt.

And every point of this curve is a solution of that polynomial.

I know I have made a small answer too much big...Sry for that...

But HOpE YouR DoUbTS are clear.
