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.
