Question

The degree of the polynomial: (x+1)(x² -x - x³ +1)

Answer 1

The degree of the polynomial is 3

Answer 2

Step-by-step explanation:

= (x + 1) ( x²- x - x³ + 1 )

= x ( x² - x - x³ + 1 ) + 1 ( x² - x - x³ + 1 )

= x³ - x² - x⁴ + x + x² - x - x³ + 1

= - x⁴ + 1

As, highest power of variable ( x) is 4,

so degree is 4
