Which statement about the following equation is true?
2x^2-9x+=-1

The discriminant of a quadratic equation helps determine the types of roots that can be extracted from the polynomial equation. The sign of the discriminant helps to do this. The formula is b^2 -4ac equal to (-9)^2 -4*2*3 equal to 57. this is over zero and there are two roots, hence.

The final answer is 3x3+6x2+8x+24+47x−2mark me brainliest
