Xy4+2x2y-3y2+10x3

Options : 1, 2, 3, 5

Arrange the following polynomial into descending order and identify the 3rd term.

-19x2+2+4x3-7x

Options : - 19x^2, 2, 4x^3 or - 7x

We arrange the polynomial in terms of the power of the variable x in descending order. The highest order is three from - 4x^3 and the lowest is 2 in which the order is zero. Hence, the polynomial becomes 4x^3 - 19x^2 - 7x + 2. The third term in this sequence is - 7x.
