what are the zeroes inclucing irrational ones of this polynomial? 9x^3-5x^2-x

Expert Answers

An illustration of the letter 'A' in a speech bubbles

To find the zeros of this polynomial first factor the x from each term (which gives a zero of 0), then determine the zeros of the remaining quadratic.

`9x^3-5x^2-x`

`=x(9x^2-5x-1)`

The second term has zeros given by the quadratic formula.

`x={5+-sqrt{25+4(9)}}/18`

`={5+-sqrt61}/18`

The zeros of the polynomial are 0 and...
