Answer:

Step-by-step explanation:
A polynomial is given to us and we need to make the polynomial by its degree . Here the given polynomial is 3x² + 5x -3 .

So here we can see that the highest power of the variable in the given polynomial is 2 . So the polynomial is a quadratic polynomial .
<u>★</u><u> </u><u>More </u><u>to </u><u>Know </u><u>:</u><u>-</u>
When we equate this quadratic polynomial with 0 , it becomes a quadratic equation.
That is ,
This is done in order to find the zeroes of the polynomial. The zeroes of the polynomial are the values for which the polynomial becomes 0 .
