Question

If graph of any polynomial cuts x-axis at two points , then the polynomial is :​

Answer 1

Answer:

A polynomial with even degree and 2 real roots

Step-by-step explanation:

A linear polynomial will cut the x-axis only once (if it has a real root) and its a line

If a quadratic polynomial has 2 real roots, the graph cuts the x-axis at those roots

Similarly, a cubic polynomial cuts the graph at its roots i.e it will cut the x-axis 3 times and so on

But there can be a polynomial with even degree which has only 2 real roots so it will also cut the x-axis 2 times only

Hope this is clear
