Determine the degree of each of the following polynomials.
(i) 4x−5x2+6x32x
(ii) y2(y−y3)
(iii) (3x−2)(2x3+3x2)
(i) 4x−5x2+6x32x
Here, the highest power of x is 2. So, the degree of the polynomial is 2.
(ii) y2(y−y3)
Here, the highest power of y is 5. So, the degree of the polynomial is 5.
(iii) (3x–2)(2x3+3x2)=6x4+9x3–4x3–6x2=6x4+5x3–6x2
Here, the highest power of x is 4. So, the degree of the polynomial is 4.
